Hi, i wanna ask bout my 2004 chevy aveo 1.5 hatchback. Check engine light appear and also the hold light blinking. Have changed the ignition coil, spark plug, spark plug wire, air filter, clean the body throttle but does not solve the problem. Plz help me someone.

Connecting it to a scan tool will give you the answer in the form of codes, AKA DTC codes. The engine light is the clue, the scan tool tells the answers via the codes. All the codes are online.

Chevy Aveo code P****

!-4 or 2-3 No 6 . Coil is bad or no control from ECM . - engine control module . Test power and control to an from coil , Test coil with ohm meter . Videos on youtube , testing ignition systems . http://www.bbbind.com/free_tsb.html wiring diagram

I would doubt that 2 injectors have gone bad at or near the same time. Low compression very well could be the issue, but you stated the car runs fine. Did you reset the codes with a scan tool? If not try that and then see if the codes return. I would check the integrity of the coil to make sure it is strong enough and getting good spark to the plugs. #2 and#3 cylinders use the same coil just as #1 and#4 use the same coil.Good luck.

My check engine light and hold light are blinking, and the car jerks alot when it's taking off.it also doesn't want to go to 4th gear ,just stays in 3rd gear even at 50mph. I've been reading online and ppl are saying it's the coil pack. I took it to O'Reilly and they say that the ignition coil 3 is bad. So I'm gonna buy the part and install it tonight or tomorrow

I have a 2009 Chevy Aveo. The hold light has come on two times since I have owned the vehicle. The first time at about 37,000 (just out of warranty)the vehicle started running very poorly. the check engine light came on as well as the hold light blinking. At first I thought it was a transmission problem, It was NOT. The problem with this gem of a car is that the spark plugs need to be replaced by 35,000 miles. The check engine light was due to the ignition coil pack being bad (cylinder 3) All four need to be replaced at once. After replacing the coil pack and plugs the check engine light went out and the hold light went out. This was an extremely easy repair. I walked my 13 year old daughter through the repair.


The second time the hold light went on was about a week ago. I now have about 52,000 miles. The light came on for no apparent reason. The only unusual thing that happened was that i accidentally spun the tires in the rain just before the light came on. The owners manual will tell you to bring it in asap because there could be serious problems. I couldn't believe i was having another major problem (there was no check engine light on this time) My guess was that the spinning of the tires could have had something to do with causing the hold light to go on and blink. What i did was disconnect the battery over night in an attempt to reset the light. It worked, i have not seen the light come back on in over a week. I drive about 50 miles a day on the highway as well as stop and go traffic. Ill call that a win.


These lights come on for a reason, if the light comes back on i will be planning on taking it in to a transmission specialist. I am not trying to say you should ignore your lights but sometimes a little effort before taking it into your mechanic can save you a bunch of money. I just wanted to share what i did with you all. Also you can have your check engine codes read my many auto part stores usually at no charge.


I would never buy another Aveo or recommend one to anyone. In my opinion they are poorly manufactured vehicles. I guess i should have guessed that any vehicle with a 3 year 36k mile warranty has such a short warranty for a reason! I hope i could help someone with my experience.

the code is in your owners manual, or call the dealership

Hi.
1. The buld holder has gone bad.
or
2. The wiring to low beam needs to be looked into.

CHECK DRL FUSE MAKE SURE ITS IN PLACE TIGHT.IF FUSE GOOD RELAY COULD BE GOING BAD.

check tps sensor (throttle position sensor in backside of the throttle cable) and map sensor (manifold absolute pressure on front little 1 inch sensor with vacuum line) make sure there plugged in. the ecm (engine control module driver side inner fender) and tcm (transmission control module under dash) both need the data to know when to upshift and increase fuel/air. Otherwise the computer runs default values and guesses off of other sensors giving poor performance. also disconnect battery for 15 min. usually resets aveo service lights if you dont have a scanner.
