The fault code is P1D9A.

The estimated repair time is 1.0 hour. The cost of fixing the fault code depends on the repair time. Most auto repair shops charge between $75 and $150 per hour.

Therefore, the fixing cost can range from $75 to $150.

The P1D9A fault code is related to the Transmission Control Module (TCM).

It occurs when the TCM detects an unexpected transmission gear ratio due to slipping clutches, hydraulic or mechanical defects, etc.

The TCM compares the actual gear ratio to a minimum and maximum calibrated gear ratio value while driving in a fixed gear, during gear engagement, and during shifting from one gear to another. The P1D9A code specifically indicates an incorrect gear ratio clutch ‘C’ or ‘D’ defect.

What are the possible causes of the P1D9A automobile fault code that triggers the engine light or service engine soon warning light?

If you see the engine light or service engine soon warning light on your dashboard, it could be due to the P1D9A fault code. This code is triggered by faulty transmission internal components. To fix it, 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 a faulty transmission internal component be diagnosed as the cause of the P1D9A fault code, and what steps can be taken to fix it?

If the engine light is on and the P1D9A fault code is displayed, it could be due to faulty transmission internal components. To diagnose the issue, check the wiring harness and connectors for any damage or corrosion. Look for broken, bent, or pushed out connector pins. Once the issue is identified, the faulty components should be replaced to fix the problem.

What are the recommended visual inspections and checks that should be performed on the wiring harness, connectors, and other components related to the P1D9A fault code?
