The Powertrain Control Module (PCM) will disable some or all fuel injectors whenever an engine RPM or vehicle overspeed condition is detected. The purpose of engine RPM/vehicle speed limiter is to prevent damage to vehicle powertrain. Vehicle will run rough, and PCM will store a continuous memory DTC P1270. When overspeed condition is over, engine will return to normal operation. If necessary, clear DTC P1270 from PCM.
