The vehicle speed sensor does this by taking note of at what rate the crankshaft is spinning.
Engine speed sensor circuit failure.
The p0725 code is a generic obd ii trouble code that notes a problem with the engine speed input circuit.
The wheel speed sensor circuitry connects to the abs module through 2 wires and a connector at each wheel speed sensor.
The engine control module ecm monitors the engine speed through the crankshaft position ckp sensor with the engine running and send signal to the.
The p0725 trouble code detects an issue with the engine speed input circuit.
There is an active diagnostic code or an easily repeated diagnostic code that is associated with either the primary engine speed timing sensor or the secondary engine speed timing sensor.
P0723 meaning the output shaft speed oss sensor provides the powertrain control module with information about the rotational speed of an output shaft the pcm uses the information to control and diagnose powertrain behavior.
Fc 277 intermittent.
The symptoms can include.
Fc 115 or fc 121 engine position engine speed circuit failure.
Fc 268 high counts.
In some applications the sensor is also used as the source of vehicle speed.
Fuel pressure in the accumulator is not changing with engine operating conditions fuel pressure sensor fault.
An engine speed sensor also known as vehicle speed sensor retrieves and sends data to your car s computer system a car speed sensor shows the car s engine spinning rate.
Check engine light turns on.
Engine speed timing sensor circuit test smcs 1912 038 system operation description.
The presence of a stored code p0725 means that the powertrain control module pcm has detected a circuit malfunction with the engine speed sensor input signal.
No engine position or speed detected at pin 17 or pin 9 of the engine harness.
The active wheel speed sensor generates a signal that is sent to the abs module.
The engine input speed sensor is responsible for sending a signal about the engine s speed to the powertrain control module pcm.
How to repair p0725 code engine speed sensor input circuit malfunction.
Use this procedure under the following situation.
What the p0725 code means.
The wheel speed sensor circuitry connects to the abs module through 2 wires and a connector at each wheel speed sensor.
The engine speed input sensor is sometimes called the transmission input speed sensor and the input speed sensor.
This type of code may be caused by a mechanical problem or an.
When the ignition is turned to the run position the abs module carries out a self test by sending a reference voltage to all of the wheel speed sensors through their circuitry to determine if they are functional.
Failure to shift gears.
