The P0714: Transmission Fluid Temperature Sensor A Circuit Intermittent refers to an issue where the transmission fluid temperature sensor A is sending an intermittent signal. This can be caused by a faulty sensor, wiring issues, or poor connections, leading to inconsistent transmission fluid temperature readings.
P0714 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P0714: Transmission Fluid Temperature Sensor A Circuit Intermittent |
| Is it serious? | Yes, as intermittent signals can cause incorrect transmission fluid temperature readings, which may lead to overheating or transmission performance issues. |
| Possible causes | – Intermittent signal from transmission fluid temperature sensor A – Faulty sensor – Wiring issues |
| How to diagnose? | – Test the sensor for intermittent faults – Inspect wiring and connectors – Replace sensor if necessary |
P0714 Meaning
The P0714 code indicates that the transmission fluid temperature sensor A is providing an intermittent signal to the transmission control module (TCM). This sensor monitors the temperature of the transmission fluid to ensure proper transmission operation. An intermittent signal can lead to incorrect readings and improper transmission control.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for other transmission-related codes that may give additional information about the sensor or related systems. | OBD-II Scanner |
| Test the Sensor for Intermittent Faults | Use a diagnostic tool to monitor the signal from transmission fluid temperature sensor A while the vehicle is running. Check for inconsistent or fluctuating signals. | Diagnostic Tool, Multimeter |
| Inspect Wiring and Connectors | Inspect the wiring and connectors associated with the transmission fluid temperature sensor for signs of damage, corrosion, or loose connections that may cause intermittent signals. | Flashlight, Multimeter |
| Test Transmission Fluid Level | Verify that the transmission fluid level is within the correct range, as low fluid can affect sensor performance. | Transmission Fluid, Funnel |
| Replace the Sensor if Necessary | If the sensor is found to be faulty and producing intermittent signals, replace it with a new sensor to restore proper temperature monitoring. | Replacement Parts, Standard Tools |
| Clear Code and Retest | After repairs, clear the P0714 code using an OBD-II scanner and take the vehicle for a test drive to ensure the issue has been resolved. | OBD-II Scanner |
| Recheck for Codes | After the test drive, re-scan the vehicle to ensure the P0714 code has not returned. | OBD-II Scanner |
