Hya,

I have a 1994 wrx and the engine check light comes on and goes off when it feels like. I have done a ecu check and the number that came up was 31 does anybody know what this code is?

Thanks Mark

 

throttle position sensor

 

Hya,

Thanks for your reply, where is it on the engine?

Mark

 

its on the passenger sider of the throttle body

 

Cheers fella

Would this cause the car to idle high, and be hesitant some time?

Thanks Mark

 

Hya,

Has anybody got a picture of one in the engine bay so I know, are these a common fault?

Thanks again Mark

 

Passenger side? It's on the opposite side to the throttle cable linkage,ie the drivers side. It;s the size of a matchbox,has a connector facing forward on it.

Hya,

Thanks alot mate for the advice.

It,s quite likley that it could cause the problems your having,as if it's faulty, the ecu won't know where your throttle is. Does your engine drop low after reving it at idle,out of gear? This again is a result of a possible tps fail.
Also, it may be out of adjustment,as i think the sensor mounting holes are slotted? But don't quote me on that!

Thanks again,

I will have to look into getting one, how much are these sensors?

Thanks Mark

 

Try putting a wanted add, someones bound to have one!
