The acceleration sensor is used to sense rough road conditions.The sensor’s signal is used by the Engine Control Module(ECM) to prevent wrongful misfire detection.
The ECM sets a DTC P1308 if the signal output is lower than threshold value.
Item | Detecting Condition | Possible cause |
Monitoring Strategy | ● Signal check Low , Signal interruption | ● Open power line ● Shorted signal to ground line ● Faulty acceleration sensor ● Faulty ECM |
Threshold value | ● Filtered acceleration sensor signal(zero point filter) : < 1.5V | |
