C1672 Mazda B2500 OBD Code

OBD/2 C1672 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.

C1672 Mazda B2500 Error Code Repair Process :

If your vehicle failed a C1672 test and the C1672 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 malfunction (bank 1 sensor 1) 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 malfunction (bank 1 sensor 1): 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 Mazda B2500 C1672 OBD2 Code

A common cause of code C1672 is the failure of O2 Sensor Circuit Malfunction (Bank 1 Sensor 1), but there are several other possible causes as well, such as ;

Erratic camshaft position due to low oil pressure
Air fuel ratio (A/F) Sensor 1 Bank 1 harness is open or shorted
Clogged or faulty fuel injector (s)
Intake Valve Timing Control Solenoid Valve circuit poor electrical connection

C1672 is a kind of Chassis Trouble Code

Diagnosing chassis noises can be one of the most frustrating problems technicians face. Fortunately, manufacturers have engineered noise, vibration and harshness (NVH) diagnostic techniques and equipment to find the source of the noise.
