DTC P0010-00: Electric Variable Valve Timing Control System: Circuit Malfunction (PYUL)

WARNING: This page is about a different variant/trim than selected.

P0010-00 (PCM (PYUL)) DETECTION CONDITION AND POSSIBLE CAUSE

System malfunction location	Electric variable valve timing control system: Circuit malfunction
Detection condition	When any of the following conditions is met. The on-board diagnostic result received from the electric variable valve timing driver determines a malfunction. Signal from electric variable valve timing driver cannot be received.
2 Fail-safe	Cut energization to the electric variable valve timing driver. Inhibits engine-stop by i-stop control.
Repeatability verification procedure	Clear the DTC recorded in the memory. (See CLEARING DTC ) Perform the KOER self test. (See DTC INSPECTION )
Inspection/action procedure	This DTC may be displayed due to the following DTCs. If the following DTCs are displayed, prioritize inspection/action. PCM (See P1380:00 [PCM (PYUL)] .) P1380:00 Proceed with the inspection/action in the order from Step 1 below. After part repair or replacement, perform the repeatability verification procedure and perform a DTC inspection. (See DTC INSPECTION ) If the DTC inspection indicates the same DTC again, go to the next step. Inspect the electric variable valve timing relay. Purpose/reason (possible cause) Electric variable valve timing relay malfunction Referred to service information item See RELAY INSPECTION ] Inspect the wiring harness (including connector/terminal) between the battery and the electric variable valve timing relay. Purpose/reason (possible cause) Malfunction in wiring harness (including connector/terminal) between battery and electric variable valve timing relay Referred to service information item (See CIRCUIT INSPECTION .) (See CONNECTOR INSPECTION .) Inspect the wiring harness (including connector/terminal) between the electric variable valve timing motor/driver and the body ground. Purpose/reason (possible cause) Malfunction in wiring harness (including connector/terminal) between electric variable valve timing motor/driver and body ground Referred to service information item (See CIRCUIT INSPECTION ) (See CONNECTOR INSPECTION ) Inspect the wiring harness (including connector/terminal) between the electric variable valve timing relay and the electric variable valve timing motor/driver. Purpose/reason (possible cause) Malfunction in wiring harness (including connector/terminal) between electric variable valve timing motor/driver and body ground Referred to service information item (See CIRCUIT INSPECTION ) (See CONNECTOR INSPECTION ) Inspect the wiring harness (including connector/terminal) between the electric variable valve timing motor/driver and the PCM. Purpose/reason (possible cause) Malfunction in wiring harness (including connector/terminal) between electric variable valve timing motor/driver and PCM Referred to service information item (See CIRCUIT INSPECTION ) (See CONNECTOR INSPECTION ) Inspect the electric variable valve timing driver. Purpose/reason (possible cause) Electric variable valve timing driver malfunction Referred to service information item (See ELECTRIC VARIABLE VALVE TIMING MOTOR/DRIVER INSPECTION ) Inspect the electric variable valve timing motor. Purpose/reason (possible cause) Electric variable valve timing motor malfunction Referred to service information item (See ELECTRIC VARIABLE VALVE TIMING MOTOR/DRIVER INSPECTION ) Replace the PCM. Purpose/reason (possible cause) PCM malfunction (no other possible malfunction considered) Referred to service information item (See PCM REMOVAL/INSTALLATION [H3T] )
