Intermittent P2135 at Startup [TPS A/B Voltage Correlation]

[CCS86]

Hi guys,

I have a Ford Racing twin 65mm TB on my boosted 2012 GT. I am running the FRPP strategy and have a lot of TPS related parameters to play with.

Only occasionally, during key on or within a few seconds of startup, I get a wrench light that eventually throws a P2135 Throttle Position Sensor A / B Voltage Correlation.

This seems to happen most on cool mornings when battery voltage is probably lowest. Usually I can clear it by keying off, then back on, waiting for a few seconds for the self test to complete without a wrench light, then startup and go.

The throttle has never shown an issue while driving, so I think it is just voltage/self-test related.

Anyone know how to slightly loosen the criteria for that self test? Someone said zeroing the hysteresis/blend values fixed it. But, this was on a 2015.

Bump. Haven't cracked it yet.
