This is a common problem with GM's. The TPS sensor goes bad in the throttle body. Throws out a message to service Stabilitrac. Not SO!!!
The kicker is that the whole throttle body has to be replaced because the TPS sensor is actually part of the throttle body!!! Costs around $250.00 for aftermarket.

SOURCE: check engine light on ,

Your check engine light is on because the computer detected a problem with the car. Take it to Autozone and they will scan for the problem.They do this for free. They can let you know what the problem is. This will take the light off also. Other auto part stores do the same service for free. Thank you for choosing FixYa.

Actually you may be losing slight power, but just can't tell. Try going to Autozone and having a FREE diagnostic done.

Stability system disabled light on no power

The stability system is software programmed into the ABS - antilock brake control module also the PCM - engine computer . service engine light DTC'S - diagnostic trouble codes stored . Your best bet , take it to a qualified repair shop or the dealer . You don't have the diagnostic equipment or knowledge to tackle this type of problem .

It runs fine but then every so often it starts losing power and alarm will go off and it flashes traction control defect on dash but no engine light last a few seconds then is fine for awhile

I would probably go ahead and have the computers scanned for trouble codes. You might find a code that would point you in the right direction to troubleshoot the problem.
It could be a low fuel pressure issue that won't set a code.
The traction control warning light can come on if the engine is having problems, as well as the braking system.

My Service ABS< stability and traction control,engine lights all are on and engine oil shows nothing on stick about 1000 miles after oil change and when I put gas in my vehicle it takes a while before...

First, the abs/traction control light is usually attributed to the abs module not receiving a speed signal from one or more wheels.

Second, if you lose less than one quart per 1000 mi. traveled, I read that this is normal. But yours is not normal. Top off the oil with the recommended viscosity.

2001 olds ABS and traction control sensor issue

An ABS sensor DOES affect the traction control system. Traction control uses these sensors to determine if a wheel is losing traction. A bad sensor will cause both the ABS and TRACTION lights to come on.
The CHECK ENGINE light however is going to be a seperate problem.
