DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Memory | Note |
---|---|---|---|---|---|---|
P136629 | "E" Camshaft Position Actuator Bank 1 Signal Invalid | Malfunction in diagnostic signal (VTM) of cam timing control motor with EDU assembly is detected for 3 seconds (1 trip detection logic). |
| Comes on | DTC stored | SAE Code: P1366 |
MONITOR DESCRIPTION
This DTC is output when a diagnostic signal malfunction is detected in the cam timing control motor with EDU assembly. The cam timing control motor with EDU assembly is equipped with a self diagnostic function, which is used to output the condition of the cam timing control motor with EDU assembly as a diagnosis signal (VTM) to the ECM. If the ECM receives a diagnosis signal that is not one of the set signals, a DTC is output immediately (1 trip detection logic).

HINT:
Read Freeze Frame Data using the Techstream. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
PROCEDURE
1. | CHECK HARNESS AND CONNECTOR (CAM TIMING CONTROL MOTOR WITH EDU ASSEMBLY - ECM) |
(a) Disconnect the cam timing control motor with EDU assembly connector.
(b) Disconnect the ECM connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
C54-4 (VTM) - C88-72 (EMD1) | Always | Below 1 Ω |
C54-4 (VTM) or C88-72 (EMD1) - Body ground and other terminals | Always | 10 kΩ or higher |
NG | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
2. | REPLACE CAM TIMING CONTROL MOTOR WITH EDU ASSEMBLY |
(a) Replace the cam timing control motor with EDU assembly.
