The P06AE: PCM/ECM/TCM Internal Temperature Sensor ‘B’ Circuit High refers to a situation where the voltage in the internal temperature sensor ‘B’ circuit of the Powertrain Control Module (PCM), Engine Control Module (ECM), or Transmission Control Module (TCM) is higher than the expected range. This may be caused by a faulty sensor or issues with the wiring in the circuit.
P06AE – Quick Overview
| Code | Information |
|---|---|
| Meaning | P06AE: PCM/ECM/TCM Internal Temperature Sensor ‘B’ Circuit High |
| Is it serious? | Yes, as high voltage can cause inaccurate temperature readings and affect module performance. |
| Possible causes | – High voltage in internal temperature sensor ‘B’ circuit – Faulty sensor – Wiring issue |
| How to diagnose? | – Test internal temperature sensor ‘B’ circuit for voltage – Inspect wiring and connectors – Replace sensor if necessary |
P06AE Meaning
The P06AE code is triggered when the voltage in the internal temperature sensor ‘B’ circuit is higher than the acceptable range. This could lead to incorrect temperature readings, affecting the performance of the control module. A faulty sensor or wiring issues, such as short circuits, are the usual culprits for this code.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for other related codes that may give further insight into the problem. | OBD-II Scanner |
| Test Temperature Sensor ‘B’ Circuit | Measure the voltage in the internal temperature sensor ‘B’ circuit and compare it to the manufacturer’s specifications. | Multimeter |
| Inspect Wiring and Connectors | Visually inspect the wiring and connectors associated with the internal temperature sensor ‘B’ for damage, loose connections, or signs of corrosion. | Flashlight, Multimeter |
| Test the Temperature Sensor | If the wiring and voltage are correct, test the internal temperature sensor itself for proper operation and replace it if faulty. | Multimeter, Sensor Test Tool |
| Clear Code and Retest | After repairs are completed, clear the code using an OBD-II scanner and take the vehicle for a test drive to ensure the issue is resolved. | OBD-II Scanner |
| Recheck for Codes | After the test drive, re-scan the vehicle to confirm that the P06AE code has not returned. | OBD-II Scanner |
