OBD-II Standard OBD-II Major Transmission

Model: SAE J2012 Extended | Code: P1324

Applicable Systems
OBD-II

Symptoms

The CVT fluid temperature has exceeded safe limits. The transmission may enter limp mode.

Possible Causes

  • CVT fluid cooler blocked or restricted
  • CVT fluid level low
  • CVT internal friction causing excess heat
  • CVT torque converter slip generating heat
  • CVT temperature sensor fault

Troubleshooting Steps

  1. Step 1: Connect an OBD-II scan tool and read all stored DTCs and freeze frame data
    All DTCs and freeze frame data are retrieved
  2. Step 2: Inspect the related sensor or actuator wiring for damage, corrosion, or loose connections
    Wiring and connectors are in good condition
  3. Step 3: Use a digital multimeter to check sensor voltage, resistance, and reference signals per manufacturer specifications
    Values are within specified range
  4. Step 4: Perform component-level testing of the suspected sensor or actuator
    Component passes or fails definitively
  5. Step 5: Clear codes and road test to verify repair
    Code does not return and system operates normally

How to Reset

To reset code P1324: 1) Repair the underlying fault. 2) Use an OBD-II scan tool to clear the DTC. 3) Perform a drive cycle to verify the monitor completes. 4) If the code returns, further diagnosis is needed.
