What is code P0727?
What the P0727 code means. The signal that triggers P0727 means that the engine speed input sensor is erratic, irrational or incorrect in some other way. Without an input speed signal that can be relied upon, the transmission in your vehicle can’t provide a useful shifting strategy.
What is the engine speed input circuit?
The engine input speed sensor is responsible for sending a signal about the engine’s speed to the powertrain control module (PCM). The PCM then uses this information to determine the proper shift strategy, which is then provided to the transmission.
When to use engine speed input circuit p0727?
Error Code P0727 is registered when the PCM is unable to receive an engine speed input signal voltage for a set period and under certain circumstances. It’s important to note that the TCM (transmission control module) or PCM may turn into limp mode when this code is stored. Other related engine speed input circuit engine codes include:
What does the p0727 code on the ECM mean?
The P0727 Codes is triggered when the TCM receives no signal from the ECM. P0727 Possible Symptoms. P0727 Meaning. The Engine Control Module (ECM) monitors the engine speed through the Crankshaft Position (CKP) sensor with the engine running, and send signal to the Transmission Control Module (TCM).
How long does it take to diagnose a p0727 code?
Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. The cost to diagnose the P0727 code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type.
What is the diagnostic code for engine speed no signal?
P0727 is a diagnostic trouble code (DTC) for “Engine Speed Input Circuit No Signal”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
