B0979 Toyota Hilux OBD Code

OBD/2 B0979 error code description and symptoms.

Throttle Position (TP) Sensor Intermittent The TP sensor circuit is monitored by the PCM for sudden TP rotation angle (or voltage) input change through the comprehensive component monitor (CCM). If during the last 80 warm-up cycles in key ON engine running the PCM detects a TP rotation angle (or voltage) changes beyond the minimum or maximum calibrated limit, a continuous diagnostic trouble code (DTC) is stored. Poor continuity through the TP sensor connectors Poor continuity through the TP harness Intermittent open or short inside the TP sensor While accessing the TP V PID on the scan tool, lightly tap on the TP sensor or wiggle the TP sensor connector and harness.

Circuit High Input codes like B0979 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 transmission 4-wheel drive high indicator short circuit to battery 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 B0979 and engine control unit are in charge of monitoring a bunch of different transmission 4-wheel drive high indicator short circuit to battery, and if they get a reading that's a little out of whack, up pops the check engine light.

Common Causes of Toyota Hilux B0979 OBD2 Code

A common cause of code B0979 is the failure of Transmission 4-Wheel Drive High Indicator Short Circuit To Battery, but there are several other possible causes as well, such as ;

Damaged VCT phaser
Faulty starter motor
Intake Valve Timing Control Solenoid Valve circuit poor electrical connection
Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection
