  • I DROVE THE CAR TO HOUSTON THIS PAST WEEKEND. THE CHECK ENGINE LIGHT CAME ON AND THROUGH A CODE PO 132. AUTO ZONE SAID IT WAS A O2 SENSOR SO I CHANGED IT AND 30 MIN LATER SAME CODE. WHAT THE CAR IS DOING IS IT IS STARTING PERFECT BUT AFTER A WHILE IT WILL NOT HOLD A IDLE AND TO KEEP IT FROM DYEING YOU HAVE TO KEEP ADVANCING IN SPEED AND IT WILL RUN PERFECT BUT IF YOU STOP IT WILL DIE. DOES NOT DO IT ALL THE TIME CAN ANYONE HELP. I DROVE IT BACK FROM HOUSTON AND DID NOT GIVE ME ANY TROUBLE ON THE WAY BACK BUT WHEN I GOT HOME IT SET FOR ABOUT 30 MIN AND I WENT TO THE STORE AND IT STARTED AGAIN... THANKS FOR ANY HELP
    PS CAR IS A 2000 CAVALIER 2.2 WITH 95 THOUSAND MILES :confuse:
  • Hi im sorry to go off subject but im a green horn to this forum and im having a little trouble figuring out where to get started.

    I have a 2004 Chevy Cavalier, It has a 2.2 liter engine, and i was wondering how many O2 sensors it has.

    My reason for asking is because I would like to know if it is possible to connect a voltage adder to the vehicle to make the computer thing it needs to lean out the fuel.

    Here is a link to a site that shows the device i want to use in my car > http://www.youtube.com/watch?v=jgHJDD6UK0A

    and here is a schematic for the device http://www.madcosm.com/apps/photos/photo.jsp?photoID=2021606

    I dont intend to use the oscillator if i dont need to.

    So basically i would like to know if i can add voltage to the 02 sensor inorder to make the ECU lean out the fuel?

    Thank you for any tips or advice you can send my way!!
  • You need to take your Ignition Control Module off, and have it tested @ an Auto Parts Store such as O'Reilly's.

    I have a 2000 Chevy Cavalier, bought secondhand. I've had it around a year... had almost no problems with it. A few weeks ago I was driving and my 'trac off' light came on and then my 'check engine' light started blinking. :( Being about 20 min from the nearest civilization, I decided to keep going until I could stop and get it checked. The car ran fine, seemed ok, just had the lights on. By the time I got to town, the lights went off and stayed off. I had no idea what to do, since it went off I decided to leave it alone. :confuse: Since then every now and again my car will repeat the performance, only now its accompanied by a weird vibration, that has gotten progressively stronger. :sick: Having experienced the runaround with another car when the check engine light came on, overcharging and no real information and a doomsday diagnosis for something small, I am hoping that i can avoid a similar process and see if anyone can help me figure out what is wrong. Thanks a bunch for any help anyone can offer on this

    I have a 97 Cavalier. The check engine/ETS off lights have been on steady for about 4 years... I can't remember the problem exactly, I think I was told it was a small leak in the gas line that no one could find...? It's been so long.

    Also, it starts kind of hard when the engine is warm. I live in northern MN and when it's -30 out, it starts right up. If the engine is kind of warm, like say I went to Target for 30 minutes and got back in the car on a nice 50 degrees day, it would start hard. Usually I get it to start by pushing the gas pedal to the floor before starting, or giving it a little gas while it is turning over (if I forgot to push the pedal down before starting).

    ANYWAY... now when the engine is warm, it is still starting hard, but temporarily the check engine light flashes. The whole car shakes and kind of smells like exhaust. I've tried letting it idle for a bit, giving it a little gas while it's idling... sometimes it works, sometimes not. Sometimes shutting it off and trying again works. Sometimes not. If I am not in a position to shut it off and try again the light stops flashing and goes back to just being on steady after 5-10 minutes. But the car is shaky whether idling in traffic or while actually driving. The shaking stops once the light stops flashing.

    I plan to bring it to the mechanic this week but in the event that it doesn't misbehave for him like it does for me (which is the norm) WHAT IS GOING ON? If it is a quirk I have to get used to, fine, if not, I don't want to make the car worse by letting it go. I have had this car since I was 16 - I am 22 now - and it has been an amazing car, I know its quirks, and I am hoping to hang on to it for awhile longer!
  • check engine light could be o2 sensor, need sparkplugs and wires, or heater coil.. ive had to replace all those.. when i had trouble with them the check engine light was on..

    I bought a second hand 1996, I have now had it for six months. The low trac light comes on when I start the car but then goes off after I drive a short distance, it also comes on when I park the car and turn the wheel to the curb. (IS THIS NORMAL, OR IS THERE A PROBLEM?) Last weekend the low trac, ets off and abs lights all came on and stayed on when I first started the car and stayed on even after driving for a few blocks. I pulled over and turned the car off and none of the lights came back on. Does anyone have any trouble shooting solutions or is this normal?

    I have a 2002 cavalier that has been in a front end collision and it has some electrical problems, [the cd player doesnt work and sometimes when i turn on the brights i get some interference and i get a buzzing noise in the speakers] the check engine and trac off light have been on since i bought the car...
    i took the speakers out of the car to see if they worked and they do work, and i used a voltage tester on the wiring up to the front speakers and im getting a reading but since the airbag went off in the collison[before i bought the car] im afraid to take the dash off... what can be done to the cd player? and can i reset the check engine/trac off without taking it to a shop? :sick:
  • I have a 1998 Chevy Cavalier, and when it gets hot out the check engine light comes on and while driving in town my temp gauge drops from normal to cold, and when it does that my trans shifts hard. But when the light come on and im driving on the highway nothing esle happen it drives fine. Any sugestions?
  • If you have the Trac Off light coming on at random times and the transmission jumping into low gear here is the answer:

    Replace the TPS (Throttle Position Sensor). $30 to $40 if you do it yourself or $70 to $95 if you have a service station do it. Of course you can pay a dealer to do it but they will charge you hundreds of dollars, (just my opinion).
    This will fix all of your problems related to the TRAC OFF light and transmission shifting into low gear.
  • Hi, I was just wondering if you, or anyone, has ever found out what this is about? I have a friend with a 2003 Cavalier with the trac off/check engine lights on. She has also recently had a problem with the coolant system, temp. gauge went way past red, but the car did not seem to actually be overheating. Then it did overheat and she had to have the thermostat and a hose replaced. Now the car only gets up to about 100 degrees and these lights are on. She is very frustrated and has been to two different shops already. All of these problems started after an emissions inspection while she was on a long drive to Ohio. Any suggestions would be greatly appreciated.
  • My 2004 cavalier has the check engine light blinking. It also idles rough, has a burning smell when the enging runs for a while, it sounds like its going to turn off after i take my foot off the gas pedal, when it first started i had to turn it three times before it finally kicked on. it sounds like it misfires and the car shakes while in idle. it wasn't able to go above 3000 rpms when i last drove it (the only time i drove it since these troubles). I changed the o2 sensor before the cat conv, the spark plugs, and the coil pack and it has the same things wrong with it. A local mechanic looked at it and said he seen milky oil on the dipstick and under the oil cap. he said it may be a blown head gasket. The following codes come up when i scan the vehicle:

    P1137 - Heated Oxygen Sensor (HO2S) Bank 1 Sensor 2 Lean System or Low Voltage
    P1138 - Heated Oxygen Sensor (HO2S) Bank 1 Sensor 2 Rich or High Voltage
    P1133 - Heated Oxygen Sensor (HO2S) Insufficient Switching Bank 1 Sensor 1
    P0137 - O2 Sensor Circuit Low Volts (Bank 1 Sensor 2)
    P0138 - O2 Sensor Circuit High Volts (Bank 1 Sensor 2)
    P0140 - O2 Sensor CKT No Activity (Bank 1 Sensor 2)
    P0136 - O2 Sensor Circuit Malfunction (Bank 1 Sensor 2)
    P0300 - Random/Multiple Cylinder Misfire Detected

    any help with be greatly appreciated, i need my vehicle for work....

    Im working on an 03 cavalier with a 2.2 ecotec. It idles and runs rough at any speed. Codes were 171 bank 1 lean, 108 map hi input 128 coolant temp not in spec and random misfire. Map was replaced, new plugs, new coil unit. TPS seems to be ok. Pulled the new plugs and they are black seems rich to me not lean. All cylinders are at 205. Any suggestions where to look.

    Thanks
  • My abs light just came on all of a sudden and i had the brakes done a few months ago and the fluid level is full. Anyone know why it would do that? :confuse:
  • I know you posted this a while ago but did you figure out what was wrong with it? My cav is doing the same thing and I don't know what it is. If you do and you could let me know that would be great. Thank you.
  • I found excessive slack in the timing chain and it had jumped a couple of teeth. The timing chain guides were also broken. Check the timing chain ASAP because you can mess up the valves and you'll have to rebuild the head.

    Good luck
  • have 05 simliar trouble, replaced tps, plugs, crank sensor, coil packs etc, just kept throwing money at it, Found out that cavaliers are real sensative to poor grounds..the cable from battery (ground) down to the battery tray was not making a good connection at the tray (body ground) was very rusty, replaced it, the same
    cable goes to the right side of the engine (stud sticking out of engine block) also the 2 wires from the main harness also hook to this stud, they were corrected a little, snipped them off put ona new connector and HOLY CRAP this car never ran this good, no propblems or lights on since.
