Ford Code P0C73 is a diagnostic trouble code (DTC) that is used to indicate a problem with the motor electronics coolant pump (MECP) control. This DTC is triggered when the TCM detects the voltage on the MECSP circuit is greater or less than what is expected. It is essential to diagnose and repair this issue as soon as possible, as it could be caused by a number of factors, including an open circuit, a short to ground, or a short to voltage. Additionally, an incorrect harness connection or a motor electronics coolant pump concern could also be to blame. To better understand this issue, be sure to check out Service Bulletin 20-2345.
Causes and Solutions for Ford Code P0C73
| Cause | Solution |
|---|---|
| MECSP circuit open | Perform a check of the circuit and repair any open connections |
| MECSP circuit short to ground | Perform a resistance check of the circuit and repair any shorts to ground |
| MECSP circuit short to voltage | Perform a voltage check of the circuit and remedy any shorts to voltage |
| Motor electronics coolant pump (MECP) concern | Replace the motor electronics coolant pump with a new part |
| Incorrect harness connection | Revisit the wiring harness and correct any incorrect connections |
MECSP Circuit Open
Ford Code P0C73 is triggered when the TCM detects an open circuit in the MECSP circuit. This can be caused by a broken wire, corrosion, or a faulty connection. To diagnose and fix this issue, it is important to perform a thorough check of the circuit and repair any open connections.
MECSP Circuit Short to Ground
A short to ground in the MECSP circuit can also trigger Ford Code P0C73. This is usually caused by a faulty wiring harness or a damaged component. To diagnose this issue, it is important to conduct a resistance check of the circuit and repair any shorts to ground.
MECSP Circuit Short to Voltage
Ford Code P0C73 can also be caused by a short to voltage in the MECSP circuit. This is usually caused by an incorrect harness connection or a faulty component. To diagnose and repair this issue, it is important to check the voltage of the circuit and remedy any shorts to voltage.
Motor Electronics Coolant Pump Concern
The motor electronics coolant pump (MECP) could be to blame for the Ford Code P0C73. If the pump is not functioning properly, it could lead to an incorrect voltage on the MECSP circuit. To fix this issue, it is important to replace the motor electronics coolant pump with a new part.
Incorrect Harness Connection
This Ford Code can also be caused by an incorrect harness connection. To diagnose and repair this issue, it is essential to revisit the wiring harness and correct any incorrect connections.
