P0014

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’m sorry it’s a 2001 XC70 190k

Check the timing marks.

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

Oil has been changed twice with mobile one 5 -30 wgt.fully synthetic . Costumes very little oil

It’s probably 1-2 teeth off
