P1136 2004 INFINITI G35 Possible Causes
What Does This Mean?
- Faulty intake valve timing control solenoid, bank 2
- Intake valve timing control solenoid 2 harness is open or shorted
- Intake valve timing control solenoid circuit, bank 2 poor electrical connection
How to Fix Code P1136 2004 INFINITI G35?
Start by checking the “possible causes” listed above. Visually inspect the corresponding wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector pins.
Technical Notes
Since the intake valve timing control solenoid uses oil flow to control timing, dirty oil can cause the valve to stick open or closed. Before replacing the valve, change the engine oil and filter and reset the engine code. If the code returns, you can remove the intake valve timing control solenoid and clean it with brake cleaner.
Possible Symptoms
- Engine light on (or service engine soon warning light)
- Possible engine misfire/loss of power
- Possible rough engine idle
P1136 2004 INFINITI G35 Meaning
The intake valve timing control solenoid is activated by pulse on/off (duty ratio) signals from the engine control module (ECM). The intake valve timing control solenoid changes the amount of oil and direction of flow through the intake valve timing control unit or stops oil flow.
Longer pulse width advances the valve angle. Shorter pulse width retards the valve angle.
When ON and OFF pulse widths become equal, the solenoid stops oil pressure flow to lock the intake valve angle at the control position.
Diagnostic trouble code (DTC) when incorrect voltage is sent to the ECM via the intake valve timing control solenoid.
