When experiencing Dodge P1273 Code, it is important to understand what is causing the problem and how to resolve it. This code is caused by a high-side driver circuit which is commanded by the Powertrain Control Module (PCM) and monitored by the Totally Integrated Power Module (TIPM). The TIPM actuates the A/C Clutch by providing voltage and monitors the circuit for correct voltage and current flow. To efficiently diagnose and fix the code, it is helpful to understand the potential causes and possible solutions.
Causes and Solutions of Dodge P1273 Code
| Cause | Solution |
|---|---|
| A/C CLUTCH DRIVER CIRCUIT OPEN | Repair any open or shorted wiring and connectors |
| A/C CLUTCH DRIVER CIRCUIT SHORTED TO VOLTAGE | Replace the A/C Clutch |
| GROUND CIRCUIT OPEN OR EXCESSIVE RESISTANCE | Inspect the ground circuit wiring and connectors |
| A/C CLUTCH | Check the A/C Clutch for any visible damage |
| TOTALLY INTEGRATED POWER MODULE (TIPM) | Replace the TIPM to resolve the issue |
A/C Clutch Driver Circuit Open
When the A/C Clutch driver circuit is open, the PCM cannot detect the correct voltage or current flow to the A/C Clutch and will set the Dodge P1273 Code. The best solution to this issue is to repair any open or shorted wiring and connectors. This will ensure that the PCM can accurately detect the correct voltage and current flow to the A/C Clutch.
A/C Clutch Driver Circuit Shorted to Voltage
When the A/C Clutch driver circuit is shorted to voltage, the PCM will detect an excessive voltage and current flow and will set the Dodge P1273 Code. To fix this issue, the A/C Clutch must be replaced to ensure the correct voltage and current flow.
Ground Circuit Open or Excessive Resistance
The ground circuit must be inspected for any open or excessive resistance, as this will cause the PCM to set the Dodge P1273 Code. The wiring and connectors must be checked for any broken or corroded connections, as this can cause an open or excessive resistance.
A/C Clutch
The A/C Clutch must be checked for any visible damage, as this can cause the PCM to set the Dodge P1273 Code. This is a common cause of this code and must be checked first.
Totally Integrated Power Module (TIPM)
The TIPM must be replaced to resolve the issue if it is found to be faulty. This is a common cause of the Dodge P1273 Code and must be checked and replaced if necessary.
Conclusion
When experiencing Dodge P1273 Code, it is essential to understand the potential causes and possible solutions. The best way to diagnose and fix the issue is to first inspect the ground circuit wiring and connectors, the A/C Clutch, and the TIPM. If any of these components are found to be faulty or damaged, they must be replaced to ensure that the PCM can accurately detect the correct voltage and current flow. In order to efficiently resolve the Dodge P1273 Code, it is important to understand the causes and solutions.
