If a condition is found, repair the loose connection at the C162 connector. Refer to DTCs P0201, P0202, P0203 and/or P0204 in SI for further circuit/system testing.
Disconnect the engine wiring harness electrical connector C162 from the fuel injector wiring harness electrical connector. The location of connector C162 (1) is next to and under the intake manifold front of engine.
Remove the TPA/cover (1) from harness connector C162.
Inspect for loose terminal tension at connector C162 (1). Check all terminals and replace as necessary. For terminal replacement, refer to Power and Signal Distribution - Wiring Systems and Power Management - Diagnostic Information and Procedures - Sumitomo Connectors in SI.
