C0766 Nissan Sentra OBD Code

OBD/2 C0766 error code description and symptoms.

The Transmission Range Sensor (also referred to as the PRNDL input an/or neutral safety switch) tells the transmission control module (TCM) an the engine control module (PCM) that the transmission is in park, reverse, neutral, drive, low, 2nd, 3rd etc. It is attached directly to the manual valve of transmission, so when the shift lever is moved from park to drive, the Transmission Range Sensor communicates this critical information to the above mentioned vehicle control module systems.

Circuit High Input codes like C0766 are mostly caused by defective alternators that develop excessive voltages, although there may be other causes as well, such as short circuits that 'leak' current into a particular system from other, unrelated systems that work on higher voltages. Note that in the case of short circuits that leak power into a control circuit, there is likely to be other, seemingly unrelated trouble codes present along with the code(s) being investigated. Diagnosing a 'high input' code will always involve a thorough testing of the charging system as a first step, followed by measures to isolate the system from all other possible sources of power during resistance, continuity, and reference voltage tests.

If your anti theft horn output circuit failure check engine light is illuminated, it's best to take it in for diagnostic testing, which can feel like a hassle. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There's a problem with the car's emissions system. The on-board diagnostics system C0766 and engine control unit are in charge of monitoring a bunch of different anti theft horn output circuit failure, and if they get a reading that's a little out of whack, up pops the check engine light.

Common Causes of Nissan Sentra C0766 OBD2 Code

A common cause of code C0766 is the failure of ANTI THEFT HORN OUTPUT CIRCUIT Failure, but there are several other possible causes as well, such as ;

Air fuel ratio (A/F) Sensor 1 Bank 1 harness is open or shorted
Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection
Damaged VCT phaser
Spark plugs may be faulty

C0766 is a kind of Chassis Trouble Code

Diagnosing chassis noises can be one of the most frustrating problems technicians face. Fortunately, manufacturers have engineered noise, vibration and harshness (NVH) diagnostic techniques and equipment to find the source of the noise.
