1A-81 Engine General Information and Diagnosis:
DTC P0340 (No. 15): Camshaft Position (CMP) Sensor Circuit Malfunction
S3RH0A1104039
Wiring Diagram
DTC Detecting Condition and Possible Cause
Reference
Connect oscilloscope between terminals “C41-11” of ECM connector connected to ECM and body ground and check
CMP sensor signal. When CKP circuit is failed (open or short), ECM identify the cylinder only by CMP sensor signal.
DTC Confirmation Procedure
1) Clear DTC.
2) Start engine and keep it at idle for 1 min.
3) Select “DTC” mode on scan tool and check DTC.
