When diagnosing a Ford vehicle with code P0C73, it’s important to figure out the root cause of the problem. This diagnostic trouble code (DTC) is set when the TCM detects the voltage on the MECSP circuit is greater than or less than the expected range. Therefore, it is necessary to identify the cause to provide an appropriate solution. This code’s possible reasons could be an MECSP circuit open, an MECSP circuit short to ground, an MECSP circuit short to voltage, a motor electronics coolant pump (MECP) concern, or an incorrect harness connection.

Common Causes and Solutions for Ford Code P0C73
| Cause | Solution |
|---|---|
| MECSP circuit open | Check the circuit for opening and repair as necessary |
| MECSP circuit short to ground | Check course for short to ground and repair as necessary |
| MECSP circuit short to voltage | Check course for short to voltage and repair as necessary |
| Motor electronics coolant pump (MECP) concern | Replace MECP or reprogram TCM |
| Incorrect harness connection | Check connections and repair as necessary |
Diagnosing Ford vehicles can be challenging, especially when dealing with code P0C73. To simplify the task, it’s important to have a breakdown of the possible causes and their solutions. This code indicates a problem with the motor electronics coolant pump (MECP) circuit, which can be caused by an open course, a short to ground, a short to voltage, an MECP concern, or an incorrect harness connection. Knowing the possible causes and their solutions can help to make the diagnosis and repair process much more efficient.
MECSP Circuit Open
One potential cause of Ford code P0C73 is an open circuit in the MECSP circuit. This can be determined by performing a series of tests on the course and checking for resistance, shorts, or continuity. The affected wiring should be inspected and repaired if an open circuit is found.

MECSP Circuit Short to Ground
Another potential cause of Ford code P0C73 is a short to ground in the MECSP circuit. This can be determined by performing a series of tests on the circuit and checking for resistance, shorts, or continuity. The affected wiring should be inspected and repaired if a short to ground is found.
MECSP Circuit Short to Voltage
Yet another potential cause of Ford code P0C73 is a short voltage in the MECSP circuit. This can be determined by performing a series of tests on the circuit and checking for resistance, shorts, or continuity. The affected wiring should be inspected and repaired if a short voltage is found.
Motor Electronics Coolant Pump (MECP) Concern
The motor electronics coolant pump (MECP) could cause Ford code P0C73. The diagnosis of this issue requires the inspection of wiring and connections, as well as a thorough examination of the MECP itself. If the MECP is found to be the cause of the code, it should be replaced, or the TCM can be reprogrammed.

Incorrect Harness Connection
The incorrect wiring harness connection can also be the cause of Ford code P0C73. This can be determined by checking the links and inspecting the wiring for any damaged, loose, or disconnected wires. If any issues are found, they should be repaired as necessary.
Conclusion
When dealing with Ford code P0C73, it’s important to understand the root cause of the issue to provide an appropriate solution. The possible causes of this code include an open MECSP circuit, a short to ground, a short to voltage, an MECP concern, or an incorrect harness connection. Knowing the possible causes and their solutions can help make the diagnosis and repair process much more efficient, allowing for a timely and cost-effective resolution.
