Afm voltage ??

[sr-rompa]

Dose anybody know what the AFM voltage should be and tps voltage be on a 20xe engine. any help would be AWSOME

Both are 5v with a common ground. Each one has a signal voltage ground back to the ecu. Signal will be in the region of between 1 and 4.5 over 0-100% range of position or mass air flow. Anything less than 1 and more than 4.5 is often regarded as 'fault' and will bring on the EML and the ECU will substitute a value to make the engine run in 'limp mode'.
