Cant find this one in any of my docs.. P01514

Wuz racing a Mustang Cobra today off a light on Hwy 121 and I heard a POP and got the "REDUCED ENGIVE POWER" & "SERVICE TRACTION CONTROL" message on the DIC.. :(

The PCM uses the TP, the BARO the IAT & the engine RPM in order to calculate & expected MAF rate.The PCM compares this value to the maf value & the speed density calculation in order to verify the proper throttle operation.

Assuming the code is P1514 (not P01514), it's a "TAC System MAF Performance", which means the the 'puter was using the TP sensor, IAT, and BARO to calculate an "expected" air flow, and compares that to what the MAF is producing. If there is too great a variance, the MIL and DTC are set. The MIL is reset after 3 consecutive drive trips and this test does not fail.

I don't know how long you've had your intake mods on, but if it happens again, especially under a load, you may want to check for intake leaks.

I don't think it's anything to worry about unless it happens again (when your not spanking Mustangs) :D
