The fault code P1DD0 indicates an issue with the hybrid battery pack coolant pump. The estimated repair time for this issue is 1.0 hour.

The cost of fixing this issue can vary depending on the auto repair shop, but it is common for them to charge between $75 and $150 per hour. Therefore, the total cost of fixing this issue can range from $75 to $150.

The P1DD0 fault code is related to the Transmission Control Module (TCM).

It monitors the pressure regulator and solenoid logic to detect a failure in their activation. The pressure regulators control the pressure to the clutches, while the solenoids activate the pressure to the parking lock and position valve.

The TCM monitors the commanded currents of all regulators and solenoids.

The code indicates a problem with the TCM monitoring processor performance, specifically unallowed engagement.

The monitoring strategies include transmission blocking, wrong driving direction, unallowed reverse engagement, and unallowed park engagement.

What are the possible causes of the P1DD0 fault code in an automobile?

If you see the engine light on or the service engine soon warning light in your automobile, it could be due to the P1DD0 fault code. This code is usually caused by a faulty Transmission Control Module (TCM), an open or shorted TCM harness, or a poor electrical connection in the TCM circuit. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can one visually inspect the related wiring harness and connectors to fix the P1DD0 fault code?

If you’re experiencing the P1DD0 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, you may have a faulty Transmission Control Module (TCM), an open or shorted TCM harness, or a poor electrical connection in the TCM circuit. To fix this issue, you should visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.

What are the consequences of ignoring the P1DD0 fault code in an automobile?
