Involved Region or Country North America
Some dealers will find a P0016 set after an engine repair that included moving the wiring harness on the right front side of the engine.
Condition
Cause
This will be a hard code and will usually cause a rough idle concern.
What we are seeing is the wiring connectors for the intake camshaft actuator solenoid bank one on
top of the engine and
the connector for the intake actuator park lock solenoid in the front of the engine for bank one,
have been swapped.
These two connectors are identical and can only be identified by wire color in the connector.
Correction:
Remove the connector and look at the schematic in eSI to compare and ensure the correct connector
is plugged into the actuator and lock solenoid. (See pictures below)
1) Bank 1 intake actuator
2) Bank 1 intake park lock solenoid
3) Same hose in both pictures for relativity.
If they are incorrect swap them back and clear the code to verify repair.
If they are already in the correct places then refer to the correct eSI diagnostics for this code.
Note: This issue is under review and this PI may be converted to a Bulletin if new information is
available.
