Decided to check and re set my TPS today as I have not long re build and fitted my plenum.

Anyway, to cut a long story short I tried to move it so as to lower the voltage reading.

It moved suddenly virtually to a dead stop with a reading of 0.15 volts. At this point I heard a rapid ticking sound, pretty sure it was some sort of electrical short coming from the passenger side of the engine.

 

I tried this a couple of times, and sure enough the same thing happened. At the same time the RPM sat at 1850 rev's.

Surely this can not be right?

 

With that I set it back to 0.44 volts but no matter what I tried, the rev's would not change.

Took her for a 8 mile drive but no difference!

 

The only thing I did notice was that the boost gauge was very lazy and she felt down on power. Normally I only have to ease the throttle on and she shows boost almost immediately. This time I felt that I really had to push her to get into boost.

 

Could I have accidentally damaged/shorted out the wast gate solenoid?

 

Any help would be most welcome as she was running fine before this mishap! Just can't understand what has changed.

Definitely sounded like an electrical short though.

Do not worry about the clicking sound, there is nothing you could of damaged whilst resetting the tps, the sound is most likely solenoids and or relays that were responding to the very low tps reading you moved it to.

 

The high tickover sound like you have lost the hard idle switch closed notification, with the ignition on unplug the large grey connector to the tps and wait about 30 seconds while it resets itself.

 

If the idle is still high it may be you have disturbed something else which is a common occurance when getting close to a zed engine!! such as a pipe, this may be why the boost seems a little more laggy, also try to tap (hard) the cold run section of the idle control valve to see if it drops the revs, this is the parts the S shaped rubber pipe goes to of the rear of the balancer bar and can get stuck sometimes.

Well, what can I say Jeff that has not been said before. You are a star mate!

Thanks once again for your exceptional advice.
