Isuzu Rodeo Check Engine Light



  • My car has been doing this for over a year...we've spent so much money..They've disconnected the cruise control and all sorts of stuff but now all they can say is we need a new computer. But in the same breath (this is the dealer) they indicate that the computer on the 2000 Rodeo "never goes bad" so the computer we need is now on a slow boat from Japan.

    It's so dangerous to drive my car...fortunately I only work about a mile from home and never take it anywhere else. It studders at all the wrong times but I find it to be more frequent during the warmer months. I actually got through the winter with little problems.

    I know it's not the computer.....It's definately electrical as the very first time it happened the car just died and all the lights, radio, etc just conked out.

    I'm not excited to spend the thousand bucks for a new computer on this car. Did you receive a reply to your post. Does anyone else knowhow this can be fixed?
  • Update on my shifting problem on 1999 Isuzu Rodeo (intermittent clunking between gears). Did alot of research and the consensus I found was that there is a transmission range sensor that apparently gets moist every time I run through puddles. If I drive for awhile, the problem always clears up (must dry out). I found an article which shows how to change it but I don't know how to attach it. Link to article is at
    Also, my CEL is definitely caused by the gas cap not being tight enough. As soon as I really crank down on it, the CEL light goes back off. Hope this helps y'all......
  • Hey, did they pull the fuse to disconnect the cruise control? We didn't have an owners manual when we bought it, i have been told that the fuse is in the box to the left of the steering wheel, you can only see it when the door is open. I would like to try and do it myself instead of spending who knows what for a shop to pull the fuse! If you can look in your manual, hopefully you have one, can you let me know which one it is?!? Also, in the event that you didn't already know this, as soon as you see the lights come up on your dash, if you push the cruise control button once, i have two places where the cruise is, but when i see the lights or feel it stutter when my foot is on the pedal, i push the button on the outside of the wiper stick (have absolutely no idea what you call the thing), and it disengages it without the car dying. Only thing that sucks is that you're constantly checking the dash! I have a 3 year old, so between being the driver, searcher for lost toys, crayons, whatever, you only have a split second to push the cruise button! It does work though. Our friend has his own shop, and just like you said "nothing comes up on the diagnostic check". How screwed up is that?!? I've checked for recalls, but so far no luck. Let me know if you find anything!! :confuse:
  • Yes. It directed me to another site. Wayns manual says item is the nutral safty switch, told how to remove take apart clean and reasemble. Havenot taken it toldly apart but cleans has helped big time. Good luck :D
  • I'm having the same exact problem with my 2001 5 Speed Rodeo, and it only seems to happen when I go over a buump in the road but it doesn't always do it, I've had the car buck when it engages and sometimes even shuts off on me. I talked to the lady that sold it to me and she said she thought her husband had fixed it because it had stopped doing it. She is suppose to get back to me tonight at work to see what the problem was. I love this truck but that gets on my nerves.
  • While driving in snowy conditions my wife, pulled in for fuel shut down the truck, after restarting: when turning on head lamps noticed left turn signal not working, turn off lights signal works but also flashes gear indicator light. Any Ideas?
  • This is what I got from the guy who had the car truck before me :

    The problem with the car before was with a part called the power steering pressure switch. It's just a small sensor that is in the pressure line of the pump itself, actually just under the hose.

    What you have to do is take out the power steering pump, which is located on your right (drivers side) if you're standing in front of the car facing it, remove the pressure line, and then if i remember right, you'll see the switch. It's kind of hard to get out because it gets lodged in there because of the pressure.

    I actually replaced it, but I was also told you can just clean it because what makes it not work right is dirt getting in the power steering fluid line, and it was dirty in there when i changed the switch before. I did clean it out, but i guess it's possible that it might have gotten dirty again.

    Another thing I was told is that you can just completely disconnect the switch all together, and the problem should go away, but I didn't even try that because i had already taken the car apart and bought the switch when I found that out.

    i can't imagine the switch went bad again in only a few months, but i guess you never know with cars. Maybe a cleaning is all it would need though, but the thing is that you have to take everything apart just to clean it anyway.

    I have the Haynes manual that explains what to do, but the picture they have in it is actually from an older Rodeo, so it really wasn't all that helpful anyway. It does give the directions though on what to do, so if you want it, you can have it.

    Hopefully this helps

    All I did was disconnect the two plugs that are near the power steering pump and cleaned them out and sorta re attached the PCM....I cant believe how dirty these things get . clean out the plugs first.. That's what I did and it hasn't done it for me in a week. Maybe that sensor is bad on yours or maybe those two plugs might need to be cleaned and re attached. I'm just glad the problem hasn't occurred in a week.
  • Why would the PCM affect the cruise control light and the transmission light ?

    When you made the change, did if fix the CC light and the Trans light problem?

    Can an idiot do this himself.

    I have the same problem and now I'm going to take my car to the transmission center to have it checked, did you ever figure out why the cruise control and trans light keep coming on and now mine is not even driveable, because it almost instantley dies out

    When the car starts the rear windshield wipers come on and also the check engine light........what do we check? Turning off the windshield wipers does not work.........
  • I recently bought an isuzu rodeo 2001, manual, 4 cyl. the check engine light is on, i took it to discount auto parts and they did a scan check, what came up with was the camshaft position sensor, i bought it, but now i am trying to figure out where does it go? can i get some help on this. :P

    I bought a used 1998 Rodeo in April and have had nothing but problems! The check engine light has come on again. I took it to Good Year and they say that they can not complete the scan and that I have to take it to the dealership. Anyone else ever heard of this? I am worried the dealership will rip me off!
  • I have a 1996 Rodeo manual 5 speed with the check engine light on. I too was told to go to the dealership, and like you I am afraid of being ripped off. I had made an appt. to have it scanned by the dealership to at least tell me what code was coming up and my husband made me cancel it, that was two weeks ago. I think I am going to go a head and reschedule the appt. but first, I will ask the dealership if they will guarantee the result of the scan. I don't want to pay big money for nothing. Have you found anything out yet about your check engine light?
  • I also have a 2000 Rodeo with the same pains as everyone, 63K miles 4 cyl. 5 speed and just came back from the dealers. After spending $105. for diagnostics was told I needed a new PCM for another $1000. Of course this is after I changed out the fuel sending unit in the tank. What the !@#$??
    I asked if I got the new PCM installed is there any guarantee that it, the fuel gage, would be fixed? No, was what He said, could be something else, but we won't know until we replace it. Isn't this supposed to be a professional car manufacturer & dealership. I know if I tried this flavor of troubleshooting in my line of work I wouldn't be around very long. It's called "shotgunning", when you don't have a clue what the real cause of the fault is, this is what you do. Change out everything at the customers expense and eventually you might get the thing fixed.
    How can they get away with this kind of crap in the United States of America?
  • I know the Amigo isn't the same as a rodeo but more of a baby rodeo. I purchased a 99 amigo with the v-6 and 4 wheel drive. The check engine light was on but I was told it just needed reset. After one week and about 1500 miles, it just died this morning. I bought and installed a new filter. Then I ran a fuel pressure test. I'm pushing about 40psi. Recommended is 47 to 55psi. Pump is weak but after it cools, it'll crank anr run for a bit but then dies again. I pulled plug after it died and the combustion chamber is dry. After 10 or 15, it'll crank back. I checked the injector while cranking, and it's not juicing enuff to start back. If I keep trying, it will start again and run for 10 or 15. Then it dies again. Somebody please help!!! This is my daily driver. I'm a college student and work construction full time too. I need to be running soon. Any ideas??? I really appreciate any help.
  • I'm not a mechanic but have you tried to reset everything by unhooking the battery? I did this on mine and the light went on for a bit. Until the problem returned. Just a thought...
  • not sure on the 4 cyl but on the v-6, it's on the rear of the driver side head under the intake. Hard to get to. It's on the head somewhere.
  • I have a 99 Amigo and the check engine and check transmission light both cam on at the same time.Everything seemsto be running ok and I havent had any shifting problems but the lights will not go off. Any suggestion to what the problem could be?
  • I have the same problem but 2002 4 cyl auto. Did you ever find location of sensor? I read something about under cam cover near the distributor cap. Do you have the correct part number?
  • found this online, again please let me know how you did if you already replaced. How long did it take?

    look at the top of the engine, the cover for the spark plugs ends at the front of the engine. Right at that point is where the connector is, to get at the sensor you must remove the serpentine belt, wiring cover, and timing belt cover, and the sensor bolt can be accessed between the camshaft pulleys, its a small torx bolt.
