B0047 Mercedes-benz Mcc OBD Code

OBD/2 B0047 error code description and symptoms.

The Transmission Fluid Pressure Switch allows the engine's control module (PCM) or Transmission Control Module (TCM) to use hydraulic fluid to engage the clutches in the transmission to allow for smoother shifting while driving. If the PCM or TCM detects an issue with the hydraulic clutch or the pressure switch, the PCM or TCM will set code B0047

Gear changes are accomplished by a command from the TCM to energize the clutch actuator to release the clutch; after which various actuators inside the transmission disengage the current gear, and depending on current operating conditions, engage the next higher or lower gear ratio. All of this happens much faster than a human driver could change gears, and in most applications, gear changes are as smooth and seamless as on any fully automatic transmission.

B0047 Mercedes-benz Mcc Error Code Repair Process :

If your vehicle failed a B0047 test and the B0047 Check Engine Light is NOT on, chances are you have a problem with the OBDII system, a burned out MIL lamp, or a faulty catalytic converter. The converter is essentially an afterburner that cleans up the exhaust after it exits the engine. The OBDII system uses o2 sensor circuit slow response (bank 2 sensor 1) a ownstream oxygen sensor to monitor the efficiency of the converter, and it should detect a drop in converter efficiency if the converter has been contaminated or is failing (ignition misfiring, leaky exhaust valves, and oil burning can all damage the converter). What you want to look o2 sensor circuit slow response (bank 2 sensor 1): Any conditions that might cause ignition misfire, an overly rich or lean fuel condition, or loss of compression. Use your OBD Express DIY to look at the oxygen sensor outputs, coolant temperature, airflow, calculated engine load, and inlet air temperature.

Common Causes of Mercedes-benz Mcc B0047 OBD2 Code

A common cause of code B0047 is the failure of O2 Sensor Circuit Slow Response (Bank 2 Sensor 1), but there are several other possible causes as well, such as ;

Continuous oil flow to the VCT piston chamber
Failures of clutch motion/travel sensors.
Faulty Air fuel ratio (A/F) Sensor 1 Bank 1
Three way catalyst converter Bank 1
