First diagnose C0191 PONTIAC code
Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
Cost of diagnosing the C0191 PONTIAC code
Labor: 1.0The cost of diagnosing the C0191 PONTIAC code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
C0191 PONTIAC Possible Symptoms

C0191 Pontiac DescriptionThe ignition 1 circuit supplies 12 volts to the longitudinal accelerometer. When the vehicle is not moving, or is being driven at a constant, steady speed, longitudinal acceleration is 0 m/sec/sec (0 ft/sec/sec) and the longitudinal accelerometer signal voltage is very near 2.5 volts. This is referred to as longitudinal accelerometer bias voltage. Vehicle acceleration or deceleration causes the longitudinal accelerometer signal voltage to increase or decrease. The harder the acceleration or deceleration, the greater the change in signal voltage.
