P057C Mitsubishi Diamante OBD Code

OBD/2 P057C error code description and symptoms.

HO2S Sensor Circuit Malfunction (HO2S-11) During testing the HO2S Heaters are checked for opens/shorts and excessive current draw.
The test fails when current draw exceeds a calibrated limit and/or an open or short is detected. Short to VPWR in harness or HO2S. Water in harness connector. Open VPWR circuit. Open GND circuit. Low battery voltage. Corrosion or poor mating terminals and wiring Damaged HO2S heater. Damaged PCM.

Some systems require that the actuator has an adequate supply of brake fluid. Low brake fluid levels can mimic the symptoms of code P057C, so consult the manual to locate the brake fluid reservoir. Bear in mind that a low fluid level can set code P057C on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.

P057C Mitsubishi Diamante Error Code Repair Process :

If your vehicle failed a P057C test and the P057C Check Engine Light is NOT on, chances are you have a problem with the OBDII system, a burned out MIL lamp, or a faulty catalytic converter. The converter is essentially an afterburner that cleans up the exhaust after it exits the engine. The OBDII system uses theft deterrent start enable signal not correct/ main relay malfunction (power hold) a ownstream oxygen sensor to monitor the efficiency of the converter, and it should detect a drop in converter efficiency if the converter has been contaminated or is failing (ignition misfiring, leaky exhaust valves, and oil burning can all damage the converter). What you want to look theft deterrent start enable signal not correct/ main relay malfunction (power hold): Any conditions that might cause ignition misfire, an overly rich or lean fuel condition, or loss of compression. Use your OBD Express DIY to look at the oxygen sensor outputs, coolant temperature, airflow, calculated engine load, and inlet air temperature.

Common Causes of Mitsubishi Diamante P057C OBD2 Code

A common cause of code P057C is the failure of Theft Deterrent Start Enable Signal Not Correct/ Main Relay Malfunction (Power Hold), but there are several other possible causes as well, such as ;

Exhaust tube
Camshaft Position Sensor harness is open or shorted
Faulty Mass Air Flow (MAF) sensor
Ignition coils circuit poor electrical connection

P057C 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.
