P1140 Fault Code: Understanding The Description And Troubleshooting Tips
The P1140 fault code refers to the intake valve timing control performance bank in the engine.
This mechanism controls the cam phases of the intake valve continuously with a fixed operating angle.
The Engine Control Module (ECM) receives signals such as crankshaft position, camshaft position, engine speed, and engine coolant temperature. Based on these signals, the ECM sends ONOFF pulse duty signals to the intake valve timing control solenoid valve. This allows for the control of the shutopen timing of the intake valve, increasing engine torque in lowmid speed range and output in high-speed range.
The intake valve timing control solenoid valve changes the oil amount and direction of flow to adjust the valve angle.
The P1140 code indicates a performance issue with this system.
FAQ
If you’re experiencing the engine light or service engine soon warning light turning on, along with possible lack of power or rough idle, it could be due to the fault code P1140. This code is often caused by a faulty intake valve timing control solenoid valve in Bank 1, an open or shorted harness, poor electrical connection, or faulty crankshaft or camshaft position sensors. To fix this issue, visually inspect the wiring harness and connectors, checking for any damage or corrosion. Additionally, look for any broken, bent, pushed out, or corroded pins in the connectors.
