P03BC Mitsubishi Magna OBD Code

OBD/2 P03BC error code description and symptoms.

Intake Manifold Runner Control Malfunction (Stuck Open) The IMRC system is monitored for failure during continuous, key ON engine OFF or key ON engine running self-test. The test fails when the signal on the monitor pin is less than an expected calibrated range at closed throttle. IMRC monitor signal circuit shorted to PWR GND or SIG RTN Damaged IMRC actuator Damaged PCM An IMRCM PID reading approximately near 1 volt at closed throttle may indicate a fault.

Circuit High Input codes like P03BC 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 fuel rail sensor in-range low 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 P03BC and engine control unit are in charge of monitoring a bunch of different fuel rail sensor in-range low failure, and if they get a reading that's a little out of whack, up pops the check engine light.

Common Causes of Mitsubishi Magna P03BC OBD2 Code

A common cause of code P03BC is the failure of Fuel Rail Sensor In-Range Low Failure, but there are several other possible causes as well, such as ;

1Camshaft Position Sensor circuit poor electrical connection
Continuous oil flow to the VCT piston chamber
Faulty Crankshaft Position Sensor (POS)
Variable Camshaft Timing (VCT) position circuit is open or shorted

P03BC 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.
