P1661 Fault Code: Understanding The Description And Troubleshooting Steps
When your engine is running at a speed of over 600 rpm, the Powertrain Control Module (PCM) keeps an eye on the MIL Control circuit. If the PCM notices that the Actual and Commanded state of the MIL Control circuit don’t match for more than 5 seconds, it triggers the P1661 fault code.
This code specifically refers to an issue with the MIL Control Circuit.
In simpler terms, the P1661 fault code indicates that there is a problem with the circuit responsible for controlling the Malfunction Indicator Lamp (MIL). The MIL is the warning light on your dashboard that alerts you to any potential issues with your vehicle.
So, when this fault code appears, it means that there is a discrepancy between what the PCM is commanding the MIL to do and what the MIL is actually doing.
This could be due to a wiring issue, a faulty PCM, or a problem with the MIL itself.
It’s important to address this issue promptly to ensure that any underlying problems with your vehicle are properly diagnosed and resolved.
