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 DTC P1307 if the acceleration sensor signal is less than 1.5 or greater than 3.5V during two driving cycles.
Item | Detecting Condition | Possible cause |
Monitoring Strategy | ● Rationality check | ● Poor connections ● Faulty acceleration sensor ● High resistance in ground ● Faulty ECM |
Threshold value | ● Storage value of accelertion sensor signal : > FSWALUV | |
Enable Conditions | ● Vehicle speed : = 0.0 km/h | |
Diagnostic Time | ● > 15 sec | |
MIL on condition | ● > 3 times |
While Idle : 2.3 ~ 2.7V
IG OFF : 0V
