2009 Aveo temp gague stopped working and hold light blinks on and off why did temp gague go out

If your speedometer stopped working and stays at 0 MPH, you should have your car checked ASAP. The most common causes of a speedometer that stopped working include are a faulty speed sensor, a broken gear on the speedometer, damaged wiring, or a faulty engine control unit.

if you have correct tools skill and knowledge it is. be sure lower coolat level in engine

Chevrolet Aveo LS where is the coolant temp sensor located

Dec 28, 2013 - Well we noticed that after the MAF sensor, the tube that conects from the MAF to the throttle body has a tear in it. So of course, this is something ...

we had to change are coolent senser. that stopped the hold light from flashing and the check engine light went off also.

Could be a misfire in one of the cylinders try changing your spark plugs

my 2009 aveo hold light and rpm gauge stop working at the same time,what we did was change the coolent sencer. that worked

Ignition misfire, how where the sparkplug boots, they have a tendency to leak toward ground, the coil fail easy and you may need to replace that as well

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.

Is it a 2009 or a 2005 do not mess with the air bag system unless you really know what you are doing.
I have found that this usually the sdm (the main module for the air bag system). Really needs to go to the dealer.

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.
