P0AF5 Chevrolet K-20 OBD Code

OBD/2 P0AF5 error code description and symptoms.

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 P0AF5, so consult the manual to locate the brake fluid reservoir. Bear in mind that a low fluid level can set code P0AF5 on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.
