P1136 Info...

Component Description
Intake valve timing control solenoid valve is activated by ON/OFF pulse duty (ratio) signals from the ECM.

The intake valve timing control solenoid valve changes the oil amount and direction of flow through intake valve timing control unit or stops oil flow.

The longer pulse width advances valve angle. The shorter pulse width retards valve angle.

When ON and OFF pulse widths become equal, the solenoid valve stops oil pressure flow to fix the intake valve angle at the control position.



CONSULT-II Reference Value in Data Monitor Mode

DTC Confirmation Procedure

Diagnostic Procedure

Component Inspection

INTAKE VALVE TIMING CONTROL SOLENOID VALVE

1. Disconnect intake valve timing control solenoid valve harness connector.



2. Check resistance between intake valve timing control solenoid valve as shown. If NG, replace intake valve timing control solenoid valve. If OK, go to next step.
3. Remove intake valve timing control solenoid valve.



4. Provide 12 V DC between intake valve timing control solenoid valve terminals and then interrupt it. Make sure that the plunger moves as shown in the figure. CAUTION: Do not apply 12 V DC continuously for 5 seconds or more. Doing so may result in damage to the coil in intake valve timing control solenoid valve. If NG, replace intake valve timing control solenoid valve. NOTE: Always replace O-ring when intake valve timing control solenoid valve is removed.

I have my z Boosted, my comp flashed and one time I was driving it started to backfire and giving me pulls like when ur out of gas, I put a scaner and it read that it was running lean, I had just finish putting gas so I draing the gas thinking it was bad gas and the problem was gone. After a week the car did it again only this time the car backfire and dashboard lights went out,I checked and im not getting any spark in the coils.
Any idea what can it be? This is a diferent engine though cause the fist one blew up.
The comp flash was in an 03 engine, this one is an 05 engine..any diference?
Thank you.. Anibal

My car threw an "Unknown DTC" from an AutoTap OBDII sensor. The tech said my mass airflow sensor had to be relearned because I have an intake? Is that right? He said they use a Solaris.

So i have this 2 codes and the guys from AutoZone were not very helpful since i felt they just read the code and repeted to me what they were but no help in how to fix them. :-(
Let me start by saying im not very familiar with 350z this is my first and before the SES came on all i did was install a backup camera and wired it to the backup lamp. After that i took the car for a short ride and notice the SES light on took it to AutoZone but no help.
Codes are:
P0182
P0462.
Please help me to fix it. I hate SES.
