I replaced timing components on 2012 gen 1 3.5L ecoboost due to cam phaser failure. After reassembly and start-up system posted DTC errors P0340, P0344, P0365 and P0365 while running rough and idling down to 500-600 rpm. Sluggish parked revving to 1500 rpm with throaty exhaust noise and won’t to 3000 rpm and then slowly dials back to mid 2000 with full pedal. Poor drive performance on short around the block test.

Followed Chilton’s DR diagnostics to identify the cause. On DR16 CHECK THE CMP SENSOR CIRCUITS FOR A SHORT TO GROUND, the SIGRTN goes to ground which it indicates is faulty. On DR17 CHECK THE CMP SENSOR CIRCUITS FOR A SHORT TO VOLTAGE, the CMP11 and VBPWR both have a voltage (11.6 and 11.3v). CMP21 and its VBPWR also have those same voltages despite no bank 2 errors (DTC codes for bank 2 do appear if CMP21 is disconnected and engine started). The voltage is present on the PCM pins and all harness continuity tests appear normal. Sensors appear to function normally on probing with multimeter and oscilloscope response on bench test with 12v power supplied.

Can a forum member confirm what voltage should be present on PCM pins for the F150 at KOEO? Testing presently appears to point to PCM fault.

Thanks,
