I have a magna Executive with a o2 sensor. I have been having problems with ever since I had to replace the main computer under the dash. I keep getting chech engine wring lights on my dash. Since then I have had the engine checked and the o2 sensor repalced only thave to problem come back to me again and again and going back to the dealer. So I disconnected the sensor from the engine to the computer and the engine still starts and I get excelleration and the car runs, though it does run sluggish and feels fuel strvations is there, but yes you can run the car without the o2 sensor especially in a Magna TR....

No it will not. As a matter of fact, the O2 sensor is actually being ignored when you start the car, until it goes into closed loop mode. O2, no. TPS, possible.

A TPS is a variable resistor that tells the engine computer the absolute throttle opening percentage. A switch tells the system when the throttle is wide open for enrichment purposes.

The TPS (throttle position switch) is attached directly accross from where the throttle cable attaches to the throttle body. It is held on with 2 torx type screws.

I had the same problem, so I changed the throttle position sensor and the camshaft sensor as well...it worked for me, hope it works for you too. also change the map sensor that was the reason the light was on
