Where can I find the exhaust back pressure sensor on a Mercedes Sprinter van?

In a Mercedes Sprinter, the back pressure sensor is situated towards the rear of the engine by the firewall on the right side of the turbo. This sensor incorporates a potentiometer to adjust the voltage detected by the CDI control unit when there are fluctuations in exhaust back pressure. If you notice a loss of power, sluggish acceleration, unresponsive throttle or find yourself stuck in limp mode, the sensor might be faulty. To replace it, you'll require a 27mm deep well socket, a ratchet, and a new sensor, which typically costs about $75, depending on your source. To swap it out, first disconnect the electrical connection, then use the socket to unscrew the sensor in a counterclockwise direction. Remove the old sensor and install the new one, taking care not to cross-thread it. Tighten it by hand first and then give it an additional quarter turn.
