Owners of 2002-07 Mitsubishi Lancer models with 2-liter engines may come into your store with a complaint that their vehicle is sometimes difficult to start, or won't start at all. The starting troubles may be accompanied by an illuminated Check Engine light, with trouble code P0335 and/or P0340 stored in PCM memory.
One likely cause for all these symptoms, Mitsubishi Motors North America Inc. said, is a damaged cam-sensor support. The support gets damaged due to lack of lubrication. Installing a new-design support with special oil grooves to increase oil flow, part No. 1865A128, should prevent further starting trouble.
Before reinstalling the cam-position sensor, make sure you clean out the metal shavings and other debris that may be present.
