Set my Pf09 Tps today to 0.35volts and it revs to over 2000rpm! at idle.
Even when i screw the idle right in it make hardly any difference,the only way it will idle is for me to set the tps at around 0.15v which is wrong isnt it?

Any help greatfully received

 

0.15 Volt is perfect. Anything between 0.06 and 0.29 is acceptable.

 

Was always told that 0.35v was how it had to be, confused now lol

 

Then you have been told wrong. You even proved it yourself, by setting the tps to 0.15V.
The idle position will be learned by the ecu, but within limits.
Below 0.05V is an error and above 0.30V is considered partial load - not idle.

 

Many thanks, guess you gotta learn as go along
