To diagnose the P1309 KIA code, it typically requires 1.0 hour of labor. The specific diagnosis time and labor rates at auto repair shops can differ based on factors such as the location, make and model of the vehicle, and even the engine type. It is common for most auto repair shops to charge between $75 and $150 per hour.
If the value exceeds threshold value, the Engine Control Module (ECM) judged this as a fault and the P1309 is set.
The Chassis acceleration(Rough Road) sensor consists of a piezoelectric vibration pick up which detects vertical acceleration of the vehicle.The sensor signal is used by the ECM to determine the degree of vertical movement of the car, for example, on a bumpy road.Since this may also cause uneven engine running, the ECM uses the signal to distinguish the phenomenon from actual misfiring.
