P0122 Citroen C4 Aircross OBD Code

OBD/2 P0122 error code description and symptoms.

Variable Cam Timing Over-advanced (Bank 1) The comprehensive component monitor (CCM) monitors the VCT position for an over-advanced camshaft timing.
The test fails when the camshaft timing exceeds a maximum calibrated value or remains in an advanced position. Cam timing improperly set No oil flow to the VCT piston chamber Low oil pressure VCT solenoid valve stuck closed Camshaft advance mechanism binding (VCT unit) P0122 DTC is a check of the VCT unit.

Circuit High Input codes like P0122 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 p0122 throttle position sensor/switch a circuit low input 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 P0122 and engine control unit are in charge of monitoring a bunch of different p0122 throttle position sensor/switch a circuit low input, and if they get a reading that's a little out of whack, up pops the check engine light.

Common Causes of Citroen C4 Aircross P0122 OBD2 Code

A common cause of code P0122 is the failure of P0122 Throttle Position Sensor/Switch A Circuit Low Input, but there are several other possible causes as well, such as ;

Camshaft advance mechanism binding (VCT unit)
1Camshaft Position Sensor circuit poor electrical connection
Continuous oil flow to the VCT piston chamber
Ignition coils circuit poor electrical connection

P0122 is a kind of Powertrain Trouble Code

Powertrain of a modern automobile, comprising engine (with exhaust system), transmission, drive shaft, suspension and the wheels. In a motor vehicle, the term powertrain or powerplant describes the main components that generate power and deliver it to the road surface, water, or air.
