Loss Of Power: Notes
NOTE:
The PCM is equipped with an over RPM/speed limit function. If programmed speed is exceeded, fuel delivery will shut off and DTC P1270 will be set in PCM memory. Also if vehicle is equipped with a Knock Sensor (KS), a lack of power may result when vehicle is operated with a breakout box installed at PCM. KS circuits are not shielded in the breakout box, and KS signal noise may be noticed by the PCM. If this happens, spark timing will be retarded and a lack of power may result.
