DTC P1517: Intake Manifold Runner Control (IMRC) Input Error (Bank 2)
P1517 - INTAKE MANIFOLD RUNNER CONTROL (IMRC) INPUT ERROR (BANK 2)
| Description: | The IMRC system is monitored for failure during continuous or key on engine off (KOEO) self-test. Each DTC distinguishes the corresponding failed bank for IMRC actuator assemblies with dual monitor switches. The test fails when the signal on the monitor pin is outside an expected calibrated range. | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | An intake manifold runner control monitor (IMRCM) PID reading at closed throttle that is less than VREF may indicate a fault. An IMRCM PID reading near 1 volt or greater with an engine speed of at least 3, 000 RPM may indicate a fault. |
