I have P0340 codes. Replaced synchronizer and sensor. Set at TDC-
installed location tool 303-562 T96T-12200-A. Reassembled. Still have same codes! Disconnected CMP. Truck runs better with out connection!
Found transmission harness fell onto exhaust manifold and burned off most of insulation on about 10 wires. Pulled harness out and spliced all 32 wires.
(8hour Job!). Reinstalled Harness, (this is not the harness the CMP sensor is on) still getting 0340. Did pinpoint checks according to Ford manual. verified CMP is working. Found NO shorts or opens in (CMP)harness.
Could it be PCM?
Could it be CKP?...or some other sensor?
Any Ideas anyone??!!!
