B26A2 Opel Signum OBD Code

OBD/2 B26A2 error code description and symptoms.

Fuel Rail Pressure Sensor in Range But Low The comprehensive component monitor (CCM) monitors the FRP pressure for acceptable fuel pressure. The test fails when the fuel pressure falls below a calibrated value. Low fuel pressure Damaged FRP sensor Excessive resistance in circuit Low or no fuel A FRP PID value below 551 kpa (80 psi) indicates a failure Low or no fuel A FRP PID value greater than 896 kpa (130 psi) indicates a failure.

As the engine heats up and combustion becomes easier and more complete, the PCM will command the idling control valve to increase the amount of air entering the engine to suit the changing conditions. However, when the load on the engine changes, say, when some electrical consumers or other systems are either turned on or off, the PCM adapts the signal voltage to the idle control valve to ensure that the idling speed remains stable, and at the RPM specified by the manufacturer.

B26A2 Opel Signum Error Code Repair Process :

If your vehicle failed a B26A2 test and the B26A2 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 o2 sensor circuit low voltage (bank 1 sensor 2) 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 o2 sensor circuit low voltage (bank 1 sensor 2): 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 Opel Signum B26A2 OBD2 Code

A common cause of code B26A2 is the failure of O2 Sensor Circuit Low Voltage (Bank 1 Sensor 2), but there are several other possible causes as well, such as ;

Erratic camshaft position due to low oil pressure
EVAP canister or fuel tank leaks
Exhaust gas leaks
Intake Valve Timing Control Solenoid Valve harness is open or shorted
