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....

Will a bad O2 sensor or Tps throttle switch prevent a car from starting?

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.

What is the difference between a throttle position sensor and a throttle position switch?

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.

Can anyone tell you why you may briefly get a check engine light when starting up The computer code says throttle positon switch but this has now been changed and it still does it?

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

Why is there no throttle response when the check engine light comes on?

My friend is having the same problem. After some research, I've come down to it being related to the idle switch on the pedal assembly. The switch is there because your throttle is electronically controlled and the switch is a canceller. If you release the throttle but the throttle position sensor is messed up and saying that there is a throttle input the truck will try to keep revving. So the idle switch cancels any signal that is being put out by the throttle position sensor. If the Idle switch sticks, it will cancel out your input into the throttle pedal. So when you want to go, the idle switch thinks that your still in idle mode. In a nut shell, people are saying that you need to replace the throttle pedal assembly. It's relatively easy, kind of expensive though. About $220.

Where is throttle pedal position switch b on your 2000 Saturn sl 2?

The throttle position sensor is on the throttle body. That's the part of the engine that controls the amount of air allowed into the engine. To find the throttle body, follow the air intake routing toward the engine. The throttle body is the part that sits on the intake manifold. To find the throttle position sensor, follow the throttle cable to the throttle body. If it helps, have someone press down and release the throttle pedal while you're looking for the throttle body/position sensor. The throttle cable causes a shaft to turn, that's the part that controls the air coming into the engine. The throttle position sensor is connected to that shaft.

Where is the Throttle positioning sensor on a Kia Sorento?

Remove the engine shroud and locate your air intake on the left hand (passenger) side of the engine. Follow the intake to the point that it connects to the throttle body. Directly behind this connection between the throttle body and the firewall you will find the throttle position sensor. The electrical clip has a housing on it that needs to be removed before you can remove the switch. Remove the engine shroud and locate your air intake on the left hand (passenger) side of the engine.

What is a throttle performance switch for an 87 corvette?

Basically, these throttle performance switches change the value that your throttle position sensor gives the ECU. This, in effect, leads your car's computer to believe that it is reaching wide open throttle sooner. How can you do this without buying a throttle performance switch? Just put your foot to the floor faster! No matter what the manufacturer might claim, your car won't make any more power than it did before you installed the switch, you'll just feel it sooner.

It is to the left and slightly down of your throttle body.

If you unclasp that wire you will see three prongs and that is your sensor/switch. Very easy to replace.

Electronic choke. It is the air temp sensor just upstream of the air box sending info to the throttle body in conjunction with the antifreeze temp sensor, located on the rear of the block near the firewall, telling the throttle body to increase fuel via a vacuum switch beside the throttle cable on the front side of the throttle body. I think. Maybe. Who knows.
