2018 Chevrolet Sonic Engine Intake Manifold Runner Control Levers

A P2076 code on certain Chevrolet Cruze or Sonic models equipped with 1.8L ECOTEC engines often means the factory tuning arm disconnected from and disabled 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 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 tuning arm setup, inviting a similar failure down the road. This upgraded Dorman OE FIX IMRC tuning arm saves serious money, time, and hassle by allowing you to replace just the worn-out factory arm. Instead of a doomed plastic connecting ball, this arm features a rugged brass ball stud that is designed for a more secure, longer-lasting connection to the motor assembly. It requires no special tools to install, and saves money and repair time by allowing the replacement of just the failed factory arm. Its improved design is made to solidly capture the existing linkage, provide increased service life, and reduce future related repair costs.
