P0014

Post by Wardhill »

I get a p0014 code after several miles . 50 -100 miles varies. The vvt valve was replaced at one point due to spliced wires

Posting a few more details will really help us help you. Miles, year, model, engine etc. I’m guessing it’s a single VVT engine?

I can drive 60-80 mph all day long and no cel but as soon as I slow down to a crawl the cel comes on. Is this a sign of the timing being off?

Check the engine oil condition first. The oil pressure is lowest when the engine slows down.

--------------------------------------------------

ECM-644A (P0014) Camshaft reset valve. Slow control. Permanent fault

Diagnostic trouble code (DTC) information

Condition
Diagnostic trouble code (DTC) ECM-644A is stored in the engine control module (ECM) if the camshaft is not in the correct position. The engine control module (ECM) registers this as a fault as soon as the engine is started.

The engine control module (ECM) registers a fault and diagnostic trouble code (DTC) ECM-644A is stored in the engine control module (ECM) if the camshaft position (CMP) sensor flanker is not correct in relation to the engine speed (RPM) sensor.

The engine control module (ECM) registers a fault and diagnostic trouble code (DTC) ECM-644A is stored in the engine control module (ECM) if the camshaft does not rotate quickly enough in response to the control signal.

Substitute value
the variable camshaft is disabled

Possible source
Faulty position
  • camshaft belt has jumped out of place on the cogs
    defective reset valve
    mechanical fault in the Variable valve timing (VVT) unit
Faulty control
  • defective camshaft position (CMP) sensor
Control too slow
  • open-circuit in signal cable
    open-circuit in power cable
    contact resistance
    short-circuit to ground in signal cable
    short-circuit to supply voltage in the signal cable
    low oil pressure
    poor oil quality

    defective reset valve
    mechanical fault in the Variable valve timing (VVT) unit
Fault symptoms
poor performance
