after driving my car to and from spring break, i got a new batch of codes from my check engine light and they are:
p0720.. ive seen discussions about this one on the forum already

p0011.. the guy at the auto parts place said that this meant the camshaft timing was over advanced. anyone want to explain this one?

and finally
p1574.. same guy said this was the ascd vehicle speed sensor.

anyone have any experience with these codes? please share any info.

 

P0011 - Bank 1 Intake Valve Timing (IVT) control performance - There is a gap between angle of target and phase-control angle degree. Possible causes are: Intake valve timing control solenoid valve, Harness or connectors, Crankshaft position sensor (POS), Camshaft position sensor (PHASE), Accumulation of debris to the signal pick-up portion of the camshaft

See page 165 in section EC of the Nissan service manual.

P0720 - The Transmission Control Module (TCM) is not receiving the pulse type signal from the revolution sensor in the automatic transmission. Possible causes are: revolution sensor or wire harness.

See page 116 in section AT of the Nissan service manual.

P1574 - ASCD vehicle speed sensor. The ECM detects a difference values between two vehicle speed signals if they are out of the specified range. Maybe this code will disappear when you fix the P0720 code.

See page 675 in section EC of the Nissan service manual.

thanks for the info. went to rock auto and found an output speed sensor for $76 so ill be ordering that soon.
i also found a variable timing solenoid for $110, ill be getting it on my next paycheck hopefully. this is the right part, right?

 

If you ordered the Doorman part # 97611 for the speed sensor, that's the one.

For the valve timing solenoid, you need the bank 1 solenoid which is the right side of the engine.
