Engine Speed Sensor Input Circuit Incorrect Signal

The engine speed input speed sensor is generally inserted through the transmission case near the front of the input shaft.

Engine speed sensor input circuit incorrect signal. The engine speed input sensor is sometimes called the transmission input speed sensor and the input speed sensor. The p0725 code is a generic obd ii trouble code that notes a problem with the engine speed input circuit. 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. Usually there s an o ring fitted to the sensor housing to make sure the sensor makes a seal with the transmission case.

This type of code may be caused by a mechanical problem or an. A stored code p0727 may be caused by a mechanical problem or an electrical problem. Engine speed sensor g28 loose. Engine speed input circuit malfunction.

A stored code p0727 simply means that the powertrain control module pcm has detected no input voltage signal from the engine speed sensor. Engine speed sensor g28 faulty. The engine input speed sensor is responsible for sending a signal about the engine s speed to the powertrain control module pcm. P0722 output speed sensor circuit no signal p0726 engine speed input circuit performance p0727 engine speed sensor circuit no signal p0731 incorrect 1st gear ratio p0732 incorrect 2nd gear ratio p0733 incorrect 3rd gear ratio p0734 incorrect 4th gear ratio p0735 incorrect 5th gear ratio.

The engine speed sensor g28 is also used as a reference sensor for the crankshaft position and correlates with the camshaft position sensor bank 1 g40 and camshaft position sensor bank 2 g163. Check engine speed sensor g28 special notes. What the p0725 code means. Without an input speed signal that can be relied upon the transmission in your vehicle can t provide a useful shifting strategy.

How to repair p0725 code engine speed sensor input circuit malfunction 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 signal that triggers p0727 means that the engine speed input sensor is erratic irrational or incorrect in some other way. The engine speed input speed sensor is generally inserted through the transmission case near the front of the input shaft. The p0725 trouble code detects an issue with the engine speed input circuit.
