What is P0725 code?

Diagnostic trouble code (DTC) P0725 stands for “Engine Speed Input Circuit.” This code is logged when the transmission control module (TCM) does not receive a valid engine speed signal from the engine control module

engine control module

An engine control unit (ECU), also commonly called an engine control module (ECM), is a type of electronic control unit that controls a series of actuators on an internal combustion engine to ensure optimal engine performance.

(ECM).

How do I fix code P0725?

What can cause a P0720 code?

What is ignition distributor engine speed input circuit?

The purpose of the ignition/distributor engine speed sensor is to provide information to the ECM regarding the rotational speed and position of the crankshaft. With this information, the ECM is able to regulate the timing of ignition spark and the distribution of fuel.

What is engine speed signal?

Your vehicle's engine speed sensor, or vehicle speed sensor as it is also known, sends information to your car's computer about how fast the car's engine is spinning at any particular moment. The sensor does this by recording how fast the crankshaft of your vehicle is spinning.

What is P0725 Engine Code [Quick Guide]

Where is crankshaft sensor located?

The location of the crankshaft position sensor can vary from one vehicle to another. Obviously it must be close to the crankshaft, so it is most often located on the front underside of the engine. It can usually be found mounted to the timing cover. Sometimes it may be mounted at the rear or the side of the engine.

What is engine speed sensor circuit malfunction?

If the input speed sensor fails, it means your car does not know how fast it is moving, which can cause many systems to fail. The symptoms can include: Failure to shift gears. Malfunctioning speedometer. Malfunctioning tachometer.

What can cause a cam sensor code?

How much does it cost to fix a P0720?

How much will it cost to fix the problem? Costs vary depending upon the cause of the P0720 code. For example, draining and replacing transmission fluid professionally generally costs between $240-290. On the other hand, replacing an output speed sensor will likely cost somewhere between $330-380.

How much is it to fix a speed sensor?

The average cost for vehicle speed sensor replacement is between $275 and $318. Labor costs are estimated between $116 and $146 while parts are priced between $159 and $172. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location.

What is the code for crankshaft position sensor?

The OBD-II code P0335 is a generic diagnostic trouble code that stands for “Crankshaft Position “A” Circuit Malfunction.” The code is set when your car's primary computer—also known as the powertrain control module (PCM)—is unable to detect a signal from the crankshaft position sensor.

What does engine code P0715 mean?

Code P0715 is triggered when the Engine Control Module (ECM) or Transmission Control Module (TCM) detects an irregular signal coming from the input/turbine speed sensor in the transmission.

What does the code P1721 mean?

The vehicle speed sensor signal/data is collected from the 'combination meter' (i.e. gauge cluster/speedometer), then transmitted to the TCM via the CAN bus communication line. A P1721 OBDII code indicates that there is a problem with the data transmission signal.

What is code P1705?

A P1705 OBDII trouble code means that there is either a short in the circuit, or the throttle position sensor itself has failed.

Will disconnecting battery reset crankshaft sensor?

To reset the check engine light you can disconnect the battery via the negative battery terminal and let the vehicle sit for an hour before reconnecting the battery. This will drain all of the power from the electronics and clear any short term memory.

Can you drive with a broken speed sensor?

However, when it comes to wheel speed sensors, a minor-seeming glitch may turn into a major safety risk. That is why in general, it is unsafe to drive a vehicle with a broken wheel speed sensor.

Can vehicle speed sensor cause transmission problems?

Without a valid speed signal from these sensors, the PCM will not be able to correctly control the shifting of gears within the transmission. This may cause the transmission to shift roughly or more quickly than normal.

How can you tell if the speed sensor is bad?

Disconnect the sensor from the housing on the transmission, as indicated in the repair manual for your car. Disconnect the sensor's wire coupling. Using the multimeter's voltmeter connect the probes to the ground and reference wires in the connector. If no voltage is received, the sensor is faulty.

Do you have to reset ECU after changing speed sensor?

You don't need to reset anything but you can disconnect battery for say an hour if you want to do it.
