The P16D7 fault code refers to a malfunction in the internal F-CAN communication circuit of the Powertrain Control Module (PCM). The PCM is responsible for transmitting and receiving pulsing signals to and from the control modules using two signal lines, CANH and CANL. When there is an abnormality in the F-CAN communication between the FI CPU and the CVT CPU inside the PCM, and the communication is interrupted for a specified time, the P16D7 fault code is triggered.

This code indicates a problem with the internal communication circuit of the PCM.

What are the possible causes for the automobile fault code p16d7 and how can I check them?

If you’re seeing the fault code P16D7 and your engine light is on, there are a few possible causes to consider. It could be a problem with the Controller Area Network (CAN) communication, a faulty Powertrain Control Module (PCM), or an issue with the PCM harness such as an open or shorted circuit. To check these potential causes, visually inspect the wiring harness and connectors, looking for any damage or corrosion. Also, check for any broken, bent, pushed out, or corroded pins on the connectors.

How can I visually inspect the wiring harness and connectors to fix the p16d7 fault code?

If you’re dealing with the p16d7 fault code and notice that your engine light is on, it’s time to take action.
