P112 HYBRID VEHICLE CONTROL: HYBRID CONTROL SYSTEM: P0338-600: Crankshaft Position Sensor "A" Circuit High Input

DTC P0338-600 - Crankshaft Position Sensor "A" Circuit High Input

DTC P0343-601 - Camshaft Position Sensor "A" Circuit High Input

DESCRIPTION

If there is any malfunction in the communication values or pulse inputs, the HV control ECU detects it by comparing the following three speeds: the engine speed transmitted by the ECM via CAN (Controller Area Network) communication, the engine speed obtained through pulse inputs, and the engine speed calculated from the MG1 and MG2 speeds.

INSPECTION PROCEDURE

PROCEDURE

1. READ OUTPUT DTC (ENGINE)
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch ON (IG).
(c) Enter the following menus: Powertrain / Engine Control / Trouble Codes.
(d) Check if DTCs are output.
Result:
DTCs are output
YES -- GO TO RELEVANT DTC CHART
NO -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (HYBRID VEHICLE CONTROL ECU - ECM)




(a) Disconnect the H16 HV control ECU connector.




(b) Disconnect the E7 ECM connector.
(c) Measure the resistance between the wire harness side connectors.
Standard resistance (Check for open):





Standard resistance (Check for short)





(d) Reconnect the ECM connector.
(e) Reconnect the HV control ECU connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

3. INSPECT OUTPUT WAVEFORM
(a) Inspect the ECM using an oscilloscope.





(1) While the engine is idling, check the waveform between the terminals of the HV control ECU connector.
Standard voltage:






NG -- REPLACE ECM
OK -- REPLACE HYBRID VEHICLE CONTROL ECU
