When certain Chevrolet Cruze or Sonic models equipped with 1.8L ECOTEC engines throw a P2076 error code it's commonly the result of the factory tuning arm breaking, disconnecting from, and disabling the intake manifold runner control (IMRC) valve assembly. No surprise, because it relies on a push-and-snap fit between two plastic parts in continuous motion. Plastic snaps work fine for static uses - say, shirt buttons - but not for this critical underhood assembly component. Over time and miles, the factory-design arm's weak plastic ball can wear to a nub, lose its connection to the assembly linkage, and can cause the IMRC motor to burn out. The dealer's repair solution is to have you purchase a costly new intake manifold that utilizes the same weak link in the IMRC motor arm setup, inviting a similar failure down the road. This Dorman OE FIX IMRC assembly with upgraded tuning arm saves money and repair time by allowing the replacement of just the motor assembly. The improved tuning arm design is made to solidly capture the existing linkage, provide increased service life, and reduce future related repair costs.
