C1672 Holden Wb OBD Code

OBD/2 C1672 error code description and symptoms.

Mass Air Flow (MAF) Sensor Intermittent The MAF sensor circuit is monitored by the PCM for sudden voltage (or air flow) input change through the comprehensive component monitor (CCM). If during the last 40 warm-up cycles in key ON engine running the PCM detects a voltage (or air flow) change beyond the minimum or maximum calibrated limit, a continuous memory diagnostic trouble code (DTC) is stored.

One example of this would be when an automatic vehicle in placed in gear. To prevent the added drag from the torque converter and transmission from reducing the idling speed, the PCM will command the idle control valve to allow more air to enter the engine, while at the same time, adjusting the injector pulse width to inject more fuel to suit the increased amount of air. Note that the idle air control valve is closed by the PCM when the throttle plate is opened to prevent excess air from entering the engine.

Common Causes of Holden Wb 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 ;

Damaged camshaft position (CMP) sensor
Engine Control Module (ECM)
Faulty Variable Camshaft Timing (VCT) position solenoid
Fuel pressure

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.
