P1645 Fault Code: Understanding The Description And Troubleshooting Steps
The P1645 fault code refers to a problem with the Evaporative Emission Purge Solenoid Output Circuit. This code is stored in the Powertrain Control Module (PCM), which controls various outputs in the vehicle. The PCM has Output Driver Modules (ODM) that provide ground outputs for operating solenoids, relays, and other devices.
In normal operation, when the output is off, the output driver should receive 12 volts.
When the output is on, it should receive zero volts, as it is grounding the output. However, if the PCM detects that the output is receiving 12 volts when it should be off, or zero volts when it should be on, it sets a fault line low. The P1645 code specifically monitors the fault line of the EVAP control solenoid.
If the PCM detects that the EVAP Solenoid Circuit line was low for 2 seconds, with the engine running for over 10 seconds, it will set the P1645 fault code.
This indicates a problem with the Evaporative Emission Purge Solenoid Output Circuit.
FAQ
If you see the engine light or service engine soon warning light on, the fault code P1645 could be the culprit. This code is often caused by a faulty evaporative emission vent solenoid, an open or shorted harness, or a poor electrical connection in the solenoid circuit. To fix the issue, visually inspect the wiring harness and connectors for any damage. Look out for broken, bent, pushed out, or corroded pins in the connectors. Don’t forget to check the possible causes mentioned above for a thorough diagnosis.
If you’re dealing with the P1645 fault code and your engine light is on, it’s time to take action. The most likely cause is a faulty Evaporative Emission Vent Solenoid or issues with the wiring harness and connectors. To fix this, start by visually inspecting the wiring harness and connectors. Look for any signs of damage, such as broken or bent pins, corrosion, or components that are out of place. This simple step can help you identify and resolve the issue quickly.
When resolving the P1645 fault code, start by checking for damaged components and connector’s pins. Visually inspect the related wiring harness and connectors, looking for any signs of damage such as broken, bent, pushed out, or corroded pins.
