P0714: Transmission fluid temperature sensor signal that cuts in and out
Transmission fluid temperature sensor circuit intermittent
Severity: Severity not verified — if the car runs badly, have it inspected
We found no source that rates P0714. TroubleCodes.net lists transmission shift symptoms for related circuits, so how it affects driving depends on the vehicle.
It gets more serious if:
- Inspect soon: If the transmission shifts harshly or overheats, have it inspected soon.
P0714 in short
P0714 means the transmission fluid temperature sensor signal is intermittent, meaning it drops out or glitches. Wiring, a poor connection or the sensor are the usual causes. The sensor tells the computer how hot the fluid is so it can adjust shifting.
The transmission fluid temperature sensor reports the fluid temperature to the computer, which uses it to manage shift timing and converter lock-up. P0714 is the intermittent version of the temperature sensor circuit fault.
TroubleCodes.net lists wiring, poor connections, the sensor and the control module as probable causes. Since the fault comes and goes, look at connections before replacing the sensor.
Most likely causes
These are general causes for this code across vehicles. None is specific to one make or model.
Cause 1: Wiring or a poor connection to the temperature sensor
Common general cause- Why it ranks here
- TroubleCodes.net lists wiring and poor connections first, which fits an intermittent signal.
- What would change this
- Rises if wiggling the harness changes the temperature reading. Falls if the reading is smooth and connections are tight.
Cause 2: Failing transmission fluid temperature sensor
Common general cause- Why it ranks here
- TroubleCodes.net lists the sensor among the probable causes.
- What would change this
- Rises if the temperature reading jumps while the fluid is warming steadily. Falls if the reading rises smoothly.
Cause 3: Transmission or engine computer fault
Possible — needs testing- Why it ranks here
- TroubleCodes.net lists the ECM, PCM or TCM.
- What would change this
- Rises only after wiring and the sensor test good. Falls if a wiring or sensor fault is found.
What to test first
Start at step 1. Each result tells you what it means and where to go next.
Step 1: Read the stored codes, then watch the transmission fluid temperature on a scan tool as the engine warms up, looking for sudden jumps or dropouts.
Warning:Keep clear of belts, the fan and hot exhaust with the engine running, and keep the vehicle in park with the parking brake set.
IfThe reading jumps or drops out while the fluid warms steadily
It meansThe temperature circuit is intermittent. Inspect the wiring.
IfThe reading rises smoothly
It meansThe fault is not present now. Check connections and watch for it to return.
Points to: Wiring or a poor connection to the temperature sensor
Step 2: Inspect the sensor connector and harness, then wiggle them while watching the temperature reading.
Warning:Transmission and exhaust parts can be hot and the engine fan can start without warning. Let parts cool and keep hands clear.
IfThe reading changes when the harness moves
It meansRepair the wiring or connector.
Points to: Wiring or a poor connection to the temperature sensor
IfNothing changes
It meansTest or replace the sensor and have a shop test the module.
Symptoms
- Check engine light on
- Shifts that feel different when the transmission is cold or hot
How to fix
Step 1: With the engine off and cool, check that the transmission temperature sensor connector is seated and the wiring is not rubbed.
