Attessa Problem R32 Gtr

[djgtr32]

Hi

My 4wd light is staying on and i'm getting fault code 21 on the attessa computer (throttle sensor or circuit).

The car is idleing fine and is not down on power at WOT, does this mean my TPS is fine (ie: signal is getting from the TPS to the power fc) and the problem is somewhere on the circuit between my power fc and the attessa computer in the boot? assuming i am correct in thinking the signal goes from the TPS to the power fc then to the attessa computer?

Any suggestions / tips on solving this problem would be much appreciated.

Thanks

Dave

Your ECU and ATTESSA computer run off independant looms. The Power FC doesn't use the TPS only the ATTESSA.

ie. your engine/power wont be affected.

Have you got a workshop manual? That'll have a flow chart for fault finding and repairing. It's possible that the plug is not connecting properly or the TPS itself could be broken.

I had the same fault show up. Best/first thing to do is unplug the sensor on the motor & give it a quick clean (the connector pins too) & show it some love. Failing that swap it with a known good unit. It is far more likely to be the sensor/connection at the sensor end than anything to do with the ATTESSA wiring.

Thanks for the reply's guys. Will give it a clean and some tlc and see what happens.

Where do i get a workshop manual from?

Thanks
