Intake Manifold Runner Control Malfunction (Stuck Open) The IMRC system is monitored for failure during continuous, key ON engine OFF or key ON engine running self-test. The test fails when the signal on the monitor pin is less than an expected calibrated range at closed throttle. IMRC monitor signal circuit shorted to PWR GND or SIG RTN Damaged IMRC actuator Damaged PCM An IMRCM PID reading approximately near 1 volt at closed throttle may indicate a fault.
Some systems require that the actuator has an adequate supply of brake fluid. Low brake fluid levels can mimic the symptoms of code U2990, so consult the manual to locate the brake fluid reservoir. Bear in mind that a low fluid level can set code U2990 on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.

If your cylinder 3 injector circuit high check engine light is illuminated, it's best to take it in for diagnostic testing, which can feel like a hassle. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There's a problem with the car's emissions system. The on-board diagnostics system U2990 and engine control unit are in charge of monitoring a bunch of different cylinder 3 injector circuit high, and if they get a reading that's a little out of whack, up pops the check engine light.
