About P2753

P2753 is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P2753 is stored, the module has detected an open (broken or disconnected) electrical path in the monitored circuit.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P2753 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The Transmission Control Module (TCM) controls and monitors a transmission fluid cooler control valve or solenoid, which regulates the flow of automatic transmission fluid (ATF) through the cooler based on transmission fluid temperature, vehicle load, and operating conditions. By bypassing the cooler when the fluid is cold and routing fluid through the cooler when temperature climbs, the TCM keeps ATF temperature inside its optimal operating window for efficiency and longevity. DTC P2753 is set when the TCM detects an open circuit condition on the cooler control output, typically identified by...
