NOTE: If DTC P1611, P2306 or P2332 is present with this DTC, diagnose
DTCs P1611, P2306 or P2332 before diagnosing this DTC.
NOTE: If the ECM detects and stores a DTC, the ECM also stores the
engine/vehicle operating conditions under which the DTC was set. Some of
these conditions are displayed on the DRB at the same time the DTC is
displayed.
NOTE: Before erasing stored DTCs, record these conditions. Attempting to
duplicate these conditions may assist when checking for an active DTC.
NOTE: The engine oil must be at the proper level for this test to be valid.
Refer to the Service Information and ensure the engine oil level is at the
specified level.
Turn the ignition on.
With the DRB, erase ECM DTCs.
Start the engine several times, letting the engine run for at least 30 seconds at a
time.
With the DRB, read ECM DTCs.
Did this DTC set again?
All
Yes
→ Go To 2
No
→ Go To 10

WARNING: WHEN THE ENGINE IS OPERATING, DO NOT STAND IN A
DIRECT LINE WITH THE FAN. DO NOT PUT YOUR HANDS NEAR THE
PULLEYS, BELTS OR FAN. DO NOT WEAR LOOSE CLOTHING.
Refer to any Technical Service Bulletins (TSB) that may apply.
Turn the ignition off.
NOTE: This DTC implies that the engine may be contaminated by water,
engine coolant or other material due to a mechanical or service failures
such as failed gaskets, seals, cracks or incorrectly installed components.
Inspect the engine for conditions referred to in the above note.
Were any of the above conditions present?
All
Yes
→ Repair as necessary.
Perform ROAD TEST VERIFICATION - VER-2.
