C2689 Proton Gen OBD Code

OBD/2 C2689 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.

As long as the throttle plate remains closed, the idling speed and quality is controlled by the PCM via the idle control valve, and as can be seen from the above it should be clear that idle control on a gasoline engine is a complex affair. For instance, if the engine is started in sub-zero temperatures, the PCM will command the idling control valve to allow less air to enter the engine to enrich the air/fuel mixture to create a condition which is roughly analogous to how chokes worked on carburetted engines to control idling in cold weather.

C2689 Proton Gen Error Code Repair Process :

If your ignition tach circuit failure 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 C2689 and engine control unit are in charge of monitoring a bunch of different ignition tach circuit failure, and if they get a reading that's a little out of whack, up pops the check engine light.

Difficulty Level (Easy)

Repair Time (20 Min.)

Cost Prediction : $ 40-75

Common Causes of Proton Gen C2689 OBD2 Code

A common cause of code C2689 is the failure of Ignition Tach Circuit Failure, but there are several other possible causes as well, such as ;

• Damaged camshaft position (CMP) sensor
• Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection
• Damaged ECM
• Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection

C2689 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.
