TPS Readings

Post by SuperRedMR2 »

So, I finally got round to doing this.

I borrowed our electrical manager's multi-meter (doesnt give readings of 0.0 just 000 or 0000)

Here are the findings:

no gap VTA - E2 = 756 ohms

0.35mm VTA - E2 = 828 ohms

0.60mm VTA - E2 = 831 ohms

no gap VCC - E2 = 4941 ohms

Excluding the first one, i'm assuming this should read as 0.756 ohms not 756 ohms, they all fall in the tolerances the manual says.

Just curious, the vacuum pipe on the throttle body that goes to the sensor near the air filter, if that's partially blocked up, would that cause any issues?

Any advice?

Cheers

After still suffering with hot idle issues I decided to buy an inlet manifold for 99p on eBay that happened to have a TB with TPS with it.

I threw it on, on saturday without checking the TPS readings and for 70 miles I have had no hot idle issues after a long run and getting stuck in traffic.

On my old TPS connector, the tab had snapped off so the loom connector never snapped in tightly, thinking this may have been the issue...
