Isuzu Rodeo Check Engine Light

I've had my rodeo for about a year. I just had a tune up done on it and now the check engine light is on. I don't understand why because we didn't do anything weird. My boyfriend did it and he just changed the spark plugs, oil filter, fuel filter and did an oil change. Any clues?

Check post #1600 in the Rodeo forum df2000, "Isuzu Rodeo" #1600, 11 May 2005 5:12 pm
The above might link to #1600, might not :-)

Also... If during spark plugs change boots separated from the coil pack, the boot from #6 diff from others and will not sit correctly on other coils, you have to find you boot #6 and put it in correct coil pack.
good luck.
Thanks...
Upon refueling my gas tank on my 2003 Isuzu Rodeo and following the 3-clicks rule, the Check Engine Light (CEL) came on! When I stopped to make sure the fuel cap is tighten, the warning message on the fuel cap "Check Engine Light may come on" stands out like "I told you so". When I got home I got on Google and read most of the posted problems related to the CEL.
Then I disconnected the battery cables to reset the computer and waited for 5 minutes. After putting the cables back, the CEL goes away.
The 3-click rules may be 4 or 5 or bunch click to make sure that the sensor sees the cap being closed!
The CEL is a latch desgin. Once the fault is triggered it won't goes away until it is instructed to clear. One way to clear the latch is to disconnect the battery cables for about 5 minutes. There are two fuses, namely ECM Main and ECM Backup, in the fuse box under the hood on the passenger side. Maybe taking those two fuses out also resets the computer but I haven't tried it yet!
I don't know how the fuel cap sensor works though. I don't see any electrical connection out of the fuel cap!

Good luck
Have you any success finding the problem? I would be very greatful in finding out. If I find out I'll be sure to tell you .
Thanks :sick:
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?
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......
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.
When you made the change, did if fix the CC light and the Trans light problem?
Can an idiot do this himself.
thanks.
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?
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.
I'm surprised the engine even started! Glad you got that resolved.

For some reason the fuel sensor in the 2000 Rodeo will start acting up and this makes the check engine light come on. If that is the problem, it cost a little over $500 at the Isuzu dealership. They gas tank needs to be lowered to gain access to the sensor. This doesn’t cause any damage driving it with the check engine light on, I did for a year.
The dealer charged $79 to run a diagnostic on the car. I’d have this done to rule it out.

The check engine light goes on because the level sensor thinks that there is no gas in the tank. This goes away when you fill the tank full, but at 3/4 the level sensor starts to go wonky. Good luck with your truck. After I got that fixed, it became my favorite ride again.
