Carrera TPS or on/off Switch
 

Is this a throttle position sensor or just a switch?

Thanks,

I believe just a switch. One is an idle switch and the other is WOT (Wide Open Throttle). But I'll let the experts chime in...

Greg,
This is not what I wanted to read.
Thanks,

Jim,
Is yours bad?

Jim,
After looking at the Bentley manual the red part is the Full Throttle switch (same as WOT I guess) .

It's not bad as far as I know.

I am working on using a Carrera manifold assembly with a Megasquirt ECU. I was hoping that the device was a TPS so that I would have to fabricate something else...

Well, I had nothing else to do this weekend.

You could find out with a meter. If it has a variable scale rather than open/closed, you'd have what you need, correct? I'm still trying to understand these OBDI cars, but many (other makes and models) seem to have a TPS(ensor) rather than just a switch. But, the air flow device may be responsible for the signals needed by the DME in this case.

The diagram in the Bentley shows only a set of contacts in the TPS.

I'm pretty certain it is only a switch. Took one apart years`ago. Had two sets on contacts. One was for idle and the other for WFO. Input to the DME for idle circuit and full throttle maps.

Milt,
I ran an Ohm check on the device looking (expecting) for the variable resistance. When it didn't manifest itself I went to the PP forum.
I called this afternoon and ordered the TPS from Clewitt.

Jim, I used a tps from a 95 993. it was simple to make a mount for the tb and is readily available. I can send you the info if you want.

Where are you in NC?

Duke,
Livin' the dream at Ft. Bragg.
Please send the info.

I used a Bosch TPS part# 0 280 120 400 000

I don't know what it's supposed to fit, but it works on my Carrera intake.

David,
Does that TPS use a 3 pin connector?
Jim S.

No, I think it's 6 pin, but I think I only used 3 wires.

okay...this sounds like the same item that Clewett Engineering is sending. The TPS uses the first 3 pins the remaining 3 are for WOT and throttle closed. Thanks for the info!

Old thread, I know, just cleaning up... SmileWavy

Bosch part number 0 280 120 400 is the 6 pin TPS from an '86-'89 944 Turbo which is commonly used when converting the 3.2 Motronic system to an aftermarket ECU which requires a variable output from the TPS.

This part is also offered by our gracious host under Porsche part number 951-606-113-00-M14

This is a direct bolt on to replace the 3 pin throttle switch on the side of the 3.2 TB.
