C0601 Mercedes S 500 OBD Code

OBD/2 C0601 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.

Circuit High Input codes like C0601 are mostly caused by defective alternators that develop excessive voltages, although there may be other causes as well, such as short circuits that 'leak' current into a particular system from other, unrelated systems that work on higher voltages. Note that in the case of short circuits that leak power into a control circuit, there is likely to be other, seemingly unrelated trouble codes present along with the code(s) being investigated. Diagnosing a 'high input' code will always involve a thorough testing of the charging system as a first step, followed by measures to isolate the system from all other possible sources of power during resistance, continuity, and reference voltage tests.

Common Causes of Mercedes S 500 C0601 OBD2 Code

A common cause of code C0601 is the failure of Air Bag Passenger Circuit Short to Ground - Loop #2, but there are several other possible causes as well, such as ;

1Camshaft Position Sensor circuit poor electrical connection
Continuous oil flow to the VCT piston chamber
Faulty Intake Valve Timing Control Solenoid Valve
EVAP canister or fuel tank leaks

C0601 is a kind of Chassis Trouble Code

Diagnosing chassis noises can be one of the most frustrating problems technicians face. Fortunately, manufacturers have engineered noise, vibration and harshness (NVH) diagnostic techniques and equipment to find the source of the noise.
