Hi folks,

I joined this forum because it looks like the right place to get some informed opinions.

I've got a BA XR6T 5sp that is stock except the the previous owner has lowered it a bit & some aftermarket rims.

My engine management light is constantly coming on under acceleration . I took it to my local mechanic (whom I trust) he put his scanner on it & it points to an error with either the throttle body or the pedal position switch.He tells me that it could be either part is faulty or even both so the plan was to replace the cheaper part first. As replacements for these parts are quite expensive I thought I'd ask you guys what your thoughts are.

He's reset the error codes with his scanner but they return after a short drive.

The car starts ,idles & runs normally . There are no flat spots
during acceleration & I can't notice any performance loss at all.

Can you guys give me some advice on how to proceed ?

Post a pic of your TPS

If you have access to an xcal2 or 3 you can datalog both and see if one throws some strange voltages or readings throughout its full sweep.

The pedal is a PAIN to change over. If its the throttle body it's a very easy job.

What code is it actually throwing?

Not sure exactly what the code was . The mechanic used a Snap-On Solus Pro so it gave us the 2 actual code definitions.

It said Throttle body & Pedal postion switch (or similar wording).

Paulie, I've attached a pic of the TPS.

I should mention that only about 500km has passed since a full service & replacement of the inlet manifold gasket which was leaking and causing about 16 error codes.

Ok it appears you still have the old one.

Now I am not saying yours is faulty, I am just saying that the older ones are known to fail.

I'll leave that with you.

I was in the process of posting check your intake manifold gasket when my internet connection dropped out, I have seen a couple of car throw tps/pps codes due to a leak either between the mani and head or upper and lower mani.

Has you mech cleared the codes?

Yeah Ralph he cleared the codes.

I would say its your throttle position switch.

My car does exactly the same thing.

What is the actual fault code?

I would say its your throttle position switch.

My car does exactly the same thing.

And you know for sure that's the problem with your car?

It's definitely the easiest to fix . You can pick them up for $100 on ebay new
