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.

C1967 Error Code Repair Process :

If your exhaust pressure sensor high 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 C1967 and engine control unit are in charge of monitoring a bunch of different exhaust pressure sensor high, and if they get a reading that's a little out of whack, up pops the check engine light.

C1967 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.

Common Causes of C1967

A common cause of code C1967 is the failure of Exhaust Pressure Sensor High, but there are several other possible causes as well, such as ;

Damaged camshaft position (CMP) sensor
Faulty Variable Camshaft Timing (VCT) position solenoid
Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection
Oil Control Valve (OCV) circuit is open or shorted
