Diagnostic Procedure with Diagnostic Trouble Code (DTC)
Step
1 CHECK HARNESS BETWEEN ECM AND
TUMBLE GENERATOR VALVE ACTUATOR
CONNECTOR.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from tumble gen-
erator valve and ECM connector.
3) Measure the resistance between tumble
generator valve actuator and ECM connector.
Connector & terminal
(E55) No. 1 — (B134) No. 19:
(E55) No. 2 — (B134) No. 18:
2 CHECK POOR CONTACT.
Check poor contact in tumble generator valve
actuator connector.
Check
Is the resistance less than 1
!?
Is there poor contact in tumble
generator valve actuator con-
nector?
EN(H4SO 2.5)(diag)-207
ENGINE (DIAGNOSTICS)
Yes
Go to step 2. Repair the open
circuit between
ECM and tumble
generator valve
connector.
NOTE:
In this case, repair
the following:
• Open circuit in
harness between
ECM and tumble
generator valve
actuator connector
• Poor contact in
coupling connector
Repair the poor Replace the tum-
contact in tumble ble generator valve
generator valve assembly. <Ref. to
