P1135 Meaning

The Air Fuel Ratio (A/F) Sensor must reach a minimum operating temperature of 1200 degrees F to produce an accurate voltage signal. The faster the Air Fuel Ratio Sensor reaches this temperature, the sooner the sensor will start sending an accurate signal to the Engine Control Module (ECM).
To reach the required temperature, a heating element is included inside the Air Fuel Ratio Sensor. The ECM controls the Air Fuel Ratio Sensor heating element based on signals from the engine coolant temperature and engine load. The ECM controls the heater circuit by allowing current to flow to ground.
The ECM monitors the voltage signal received through the heater circuit and determines the circuit’s status by comparing the detected voltage to factory specifications.

How to fix P1135 INFINITI code?

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.

When is the code detected?

When there is a discrepancy between the target angle and the phase control angle degree, the valve will stop functioning and the Engine Control Module (ECM) will trigger the P1135 code.

Possible Symptoms

• Engine light on (or service engine soon warning light)
• Possible engine misfire/loss of power
• Possible engine rough idle

P1135 INFINITI Meaning

This mechanism hydraulically controls the cam phases continuously with the fixed operating angle of the intake valve.
The Engine Control Module (ECM) receives signals such as crankshaft position, camshaft position, engine speed, and engine coolant temperature. Then the ECM sends ON/OFF pulse duty signals to the intake valve timing control solenoid according to the driving condition. This controls the intake valve closing/opening timing to increase engine torque in the low/mid speed range and output in the high speed range.
The intake valve timing control solenoid changes the amount of oil and direction of flow through the intake valve timing control unit or stops the 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 the oil pressure flow to fix the intake valve angle at the control position.
