WORKING ON THE CHAIN GANG
Mitsubishi reports that certain instructions were missing from the repair manuals regarding timing chain inspection for the 2010 Lancer, Lancer Sportback and Lancer Evolution. Affected service manuals include 2010 Lancer, page 11C-17, Lancer Sportback, page 11A-18 and Lancer Evolution, page 11A-17. TIMING CHAIN ELONGATION VISUAL CHECK NOTE: When the timing chain elongates more than the specifed length, the DTC P0012 (variable valve timing advancedangle value abnormal) is set. Unless the code P0012 is set, the visual check is unnecessary. THE MISSING INFORMATION: After the DTCs P0016 (crankshaft/camshaft intake position sensor phase problem) and P0017 (crankshaft/camshaft exhaust position sensor phase problem) are repaired, it is necessary to delete the learning value of the timing chain elongation. At that time, perform the visual check. NOTE: Unless the work using scan tool MB991958 is correctly carried out due to the malfunction of the ECM, carry out the check whether or not the DTC exists. • Storing the learning value regarding the amount of timing chain elongation before ECM replacement. • Writing the learning value into the new ECM after ECM replacement.
Note locations of the timing marks and the chain elongation indicator.
