Hi

A mate of mine has a 1991 Sapphire 4X4 and has been having a few issues with idle and hunting on tick over.

We have checked for vac leaks and done a vac test and all is well, so my next thought was the TPS...

When i looked at it i saw that it had a "RED" TPS fitted and thought hey presto found issue as i thought all the PF01 sensors were red.

On removing the sensor is had stamped on it PF09.

Which i thought were all black.

Has anyone else go any PF09's that are red in colour ????

Cheers

 

Mine is red also. PF09 for the L8 ECU.

If you zoom and squint you can kind of see the red behind the idle speed control valve

Some pf09 are red others black, have bouth of them

 

Early ones red later ones black.

Again i have both.

 

many thanks...

I think this is the problem the reading are all over the place.

Can some one confirm what readings should be at closed throttle and throttle fully open.
( PF09 )

Thanks

 

Roughly 0.5 closed throttle to 4.5 open throttle. iirc I set mine to around 0.35 closed throttle maybe even less but can't quite remember it was that long ago
