If you receive customer reports of the check engine light being illuminated and the following fault code scenario is found in the above model vehicles,
follow the applicable procedure below to resolve.
Fault Code Scenario 1: DTC 1200 and/or 1208 are stored in ME-SFI control module. The fault codes are recorded as current and stored in the fault
memory. When the fault memory is erased and the engine is restarted, the fault codes reoccur immediately. This is due to the positioning of the camshafts
of the right cylinder bank relative to the crankshaft being impaired by a worn sprocket on the balance shaft on engine M272 or by a worn guide (idler)
gear for the timing chain on engine M273.
Applicable Models (Not Applicable to Model 204): Equipped with M272 Engine Up to Serial No. 2729..30 468993 or M273 Engine Up to Serial No.
a. Perform a visual inspection for wear of teeth on sprocket of balance shaft (M272) or of guide (idler) gear for timing chain (M273) by removing the
timing case cover on the engine.
NOTE: When inspecting the component, refer to Figure 1 for an example of a damaged gear.
