P1140 INFINITI Possible Causes

• Faulty intake valve timing control solenoid valve, bank 1
• The wiring harness of the intake valve timing control solenoid valve for bank 1 is open or short-circuited
• Poor electrical connection in the circuit of the intake valve timing control solenoid valve, bank 1
• Faulty crankshaft position sensor

How to Fix Code P1140 INFINITI?

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 ECM will trigger code P1140.

Possible Symptoms

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

P1140 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 valve based on 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 valve changes the amount of oil and the direction of flow through the intake valve timing control unit or stops the oil flow. The longer pulse width advances the valve angle. The shorter pulse width retards the valve angle. When the ON and OFF pulse widths become equal, the solenoid valve stops the oil pressure flow to fix the intake valve angle at the control position.

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 ECM will trigger code P1140.

Possible Symptoms

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

P1140 NISSAN 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 valve based on driving conditions. 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 valve changes the oil amount and flow direction through the intake valve timing control unit or stops the oil flow. A longer pulse width advances the valve angle. A shorter pulse width retards the valve angle. When the ON and OFF pulse widths become equal, the solenoid valve stops the oil pressure flow to lock the intake valve angle at the control position.
