The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.


The Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type. Also engine mechanical problems ca cause many drive-ability related problem such as rough idle and other symptoms

to all...it may be a switch problem. if it was the wiper motor, common sense says you wouldn't have any wipers at all. also have someone go over the wiper relay in your vehicles.

SOURCE: 2004 Chevrolet Aveo Brake lights not working

A couple of days ago my brake lights on my 2004 Chevy Aveo wouldn't work, so I attempted to remove the lamp covers to check the bulbs. Also, before this my shifter would get stuck in park and could only be released by pressing the unlock gadget next to the shifter. Back to the brakes...Well, you open the trunk and remove the two screws just like the manual said, but it was very hard to pull off. There's 2 prongs holding the other half of the light on. The lamp will come loose by prying it (very hard). You think the cover will break, but it'll come loose. The bulbs were all OK.

After much frustration and internet info, the STOP LAMP SWITCH, GM#96436331 ($9.30 at Chevy dealer), which is located under the dash and has contact with the brake pedal, was defective. Once replaced, both my brake lights AND SHIFTING problems were cured. So if the brake lights suddenly don't work or you have problems getting the vehicle out of park, check the switch by pushing the prong (end that has contact with brake) of the switch in and out. If it doesn't retract smoothly...that's the PROBLEM. Good Luck.

Most likely the intake gaskets are bad. they will sag in the middle over time and allow a vacuum leak between the head and intake. recommend replacing the gaskets with the steel instead of plastic ones.

Something that might sound really easy, but please check your gas cap, make sure its on real tight or the rubber seal is still good,if not, get a replacement before you try and get any mechanics to touch your car. It might save your big bucks! All the best and drive safe. Hollywood Harv

Get the code, any time you get a check light on the dash,that won't tell you what is wrong or what to replace,just what system has a possible issue

There is no common cause or problems on any vehicles, and all their hundred of parts and several systems.

O2 sensor cross talk bank to bank irregular, change 02 sensor(s).

Hold light blinking, check engine light on, engine slows down


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.
