Involved Region or Country
Condition
North America
Some dealers may experience misfires, CEL / MIL, or other drivability concerns immediately after
installing a GM re-manufactured HFV6 engine
.
Cause
This condition may be caused by a component transferred over from the original engine
that was not
supplied with the replacement engine
.
Some of the things we have seen have been camshaft actuator solenoids (OCV’s), fuel injectors and
fuel, intake manifolds, and catalytic converters.
Additionally this could be caused by a mistimed engine
or an incorrect camshaft or actuator being
installed in the incorrect location.
Correction:
If a misfire or DTC concern is found immediately after engine
installation, perform normal
diagnostics.
NOTE: Make sure the misfire or DTC is not cause by ignition, fuel, or electrical components that
were not part of the replacement engine
assembly. See below
Comparison of good vs bad Camshaft Actuator Solenoids.
The stuck solenoid pintle is shown in each photo with the open hole visible in the body of the
solenoid.
Also check to make sure the camshafts and actuators are correct and in the correct place. See Below
Camshaft Identification on HFV6.
Note last 5 characters. Of these 5 characters, the first 3 designates the RPO of the engine
, (L or
R) designates the bank, and
(I or E) designates intake or exhaust.
If normal diagnostics along with these enhanced diagnostics do not lead to the cause, prior to
removing the timing cover
or cylinder heads, call TAC and start a case for next step
recommendation.
