Mercedes Benz Code = 0319 The injection valve output stage of cylinder 2 detects a line discontinuity. (P0202)
Check the 'Possible Causes' listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.
The cost to diagnose the P0202 Mercedes-Benz code is 1.0 hour of labor. The diagnosis time and labor rates at auto repair shops vary depending on the location, make and model of the vehicle, and even the engine type. Most auto repair shops charge between $75 and $150 per hour.
This fault code is stored in the Engine Control Module (ECM) when the injector control circuit does not behave as expected. The ECM uses the induced voltage from the injector to indicate that the fuel injector circuit is operating correctly electrically. It does not signal the mechanical condition of the injector. When the ECM opens the ground circuit for an injector (to cease current flow) a voltage is induced into the winding. This voltage shows the electrical integrity of the injector and associated wiring. Absence of this induced voltage results in a fault code being stored in the ECM. This code is generated if the fault is associated with cylinder 2.
