P1077 Fault Code: Understanding The Cause And Solution
The P1077 fault code indicates a malfunction in the Intake Manifold Runner Control (IMRC) system at low RPM. The IMRC valve plays a crucial role in regulating engine power by controlling the intake manifold runner. When the valve is closed, it maximizes torque at low engine speeds, while opening the valve increases torque at high engine speeds.
However, when this system malfunctions at low RPM, it can lead to issues with engine performance and efficiency.
It is important to address this fault code promptly to ensure optimal engine operation.
FAQ
If you’re seeing the engine light on or the service engine soon warning light, the fault code P1077 could be the culprit. This code is often caused by a faulty intake manifold runner control (IMRC) valve or issues with the IMRC valve harness, such as an open or shorted circuit or poor electrical connection. To visually inspect these potential causes, check the wiring harness and connectors related to the IMRC valve. Look for any damaged components and examine the connector’s pins for signs of being broken, bent, pushed out, or corroded.
If you notice that your engine light is ON or you see a Service Engine Soon Warning Light, it could be due to a faulty Intake Manifold Runner Control (IMRC) Valve.
