1996 Grand Am Sensors?

Question

The 'check engine' light keeps coming on, on my 96 Grand Am. The code reader says something about the 'transmission sensor', but also, as soon as the 'check engine' light comes on, so does the "ETS" light.. my question is, where is the transmission sensor located, and could the 'ets' light have anything to do with the check engine light coming on...are they 'related'? (they both come on at the same time. )

ps... we were able to clear the codes for about 2 months, and the check engine (and also the ETS light) light was off for that period of time, but they are back on now.

Answer 1

ETS is enhanced traction systom The two lites are most likely related or are the same problem but i would need the trouble code from the engine computer to say witch sensor is at fault there is more than one sensor in and on the trans

Answer 2

(Check Engine Light)

There are many components that work together in the engine to maintain optimal engine performance and economy.

A service engine soon, or check engine light indicates that there is a sensor that is reading a condition that is "out of range".

Simply resetting the light does not solve the initial cause of the problem.

Replacing a number of parts trying to troubleshoot the problem in the hopes of getting the light to stay off is a tremendous waste of time and money.

The simplest, and most economical way to alleviate your issue, is to have an engine diagnostic done by a reputable shop to determine what caused the computer to signal you to begin with. Just reading the computer codes may not find the "cause".

That being said, if per-chance you feel the need to reset the light in the hopes that it was a "glitch" of some kind, you could disconnect the negative battery terminal for a couple of minutes to clear the check engine light.

Answer 3

ETS = Exhaust temp sensor.

The trans modulator is mounted on the intake manifold main vacume.You have a vacume problem,If your cat is plugging up it also heats up, thus the ets light.If there is to much backpressure in the exhaust it will change the main vacume pressure,thus the transmission sensor code.

Buy a repair manual and a vacume gauge and test pressure. May end up replacing cat.





P.S. it sounds technical but just remember it was made by man soo man can fix it.



If he wants to.
