The estimated repair time for this fault code is 1.0 hour. Auto repair shops typically charge between $75 and $150 per hour for their services.

These factors will determine the overall cost of diagnosing and fixing the p0ce9 fault code.

The P0CE9 fault code refers to a problem with the control circuit of the hybridEV electronics coolant pump in a vehicle.

This pump is responsible for circulating coolant to regulate the temperature of the power electronics coolant radiator, hybridEV powertrain control module 1, and the battery charger. The hybridEV powertrain control module 2 sends an enable signal to the coolant pump, allowing it to operate. The pump is controlled using a pulse-width modulated signal from the powertrain control module 2, with a higher duty cycle resulting in a higher pump speed.

Under normal operation, the coolant pump provides feedback on its speed to the powertrain control module 2. However, if the pump detects an internal fault, it will instead send this information on the same feedback circuit.

This fault code indicates a problem with the control circuit of the hybridEV electronics coolant pump.

What are the possible causes for the automobile fault code p0ce9?

If you see the engine light or service engine soon warning light on, the fault code P0CE9 could be the culprit. This code is often caused by a faulty hybrid/EV electronics coolant pump, an open or shorted harness, or a poor electrical connection in the pump circuit. To fix the issue, start by visually inspecting the wiring harness and connectors. Look for any signs of damage or corrosion, and check for broken, bent, pushed out, or corroded pins in the connectors. Don’t forget to check the possible causes listed above for a more comprehensive solution.

How can I visually inspect the wiring harness and connectors to fix the issue?

To fix the issue of the Engine Light being ON or the Service Engine Soon Warning Light, you can visually inspect the wiring harness and connectors. This can help identify the cause, which could be a faulty Hybrid/EV Electronics Coolant Pump or an open or shorted harness. By checking for damaged components and looking for broken, bent, pushed out, or corroded connector pins, you can pinpoint the issue and proceed with the necessary fix. Don’t forget to refer to the “Possible Causes” listed above for further guidance.

What should I look for when checking for damaged components or corroded connector pins?

When troubleshooting an engine light or service engine soon warning light, it’s important to check for damaged components and corroded connector pins. These issues can be the cause of a faulty hybrid/EV electronics coolant pump or a poor electrical connection in the pump circuit. To fix the problem, visually inspect the wiring harness and connectors, paying close attention to any signs of damage or corrosion. Look for broken, bent, pushed out, or corroded pins on the connectors.
