So I would like to understand if the live value read at idle on a cold day, should be approximately the same as on a hot day at idle.
When the ECU light had triggered (due to ST fuel trims max out at -25%, and LT -20%) and the fault still present it was reading 10g/s at 600rpm.
Normally I would see around 5g/s at idle.
Is the 10g/s defiantly a faulty sensor, or can this value be effected by external temperature/pressure (or even altitude).
When I disconnected the sensor, and have it use default values, the STFT went +25%.
It’s a 4 litre engine, year 200111/6/23
