Angle deviation of camshaft relative to crankshaft, ME-SFI fault code description - AD07.61-P-4000-77A

    Angle deviation of camshaft of right bank of cylinders relative to crankshaft
1A Fault code
(USA ONLY Display on generic scan tool)
P203D (P0370)
1B Engine 112, 113 as of 1/01 P203D-[1] Maximum angle deviation in "Advanced" direction (P0370
Fault code
(USA ONLY Display on generic scan tool)
P203D-[2] Maximum angle deviation in "Retarded" direction (P0370)
2 Fault storage After expiry of test duration and fault
Activation of the engine diagnosis indicator lamp (EURO3/4)
or CHECK ENGINE (MIL) malfunction indicator lamp USA ONLY
No activation
3 Checking frequency Continuous
4 Checked signal or status Comparison of signals from crankshaft position sensor with camshaft Hall sensor.
5 Fault setting conditions 
Checking duration
The camshaft for the right cylinder bank is offset for at least 2 s by more than 15° crankshaft angle to achieve the preset specified target position.
Less than 5 s
6 Check prerequisites
  • Engine at operating temperature
  • Engine speed between 1500 and 3000 rpm
  • Engine speed approaching constant.
  • No fault in crankshaft position sensor, camshaft Hall sensor and coolant temperature sensor.
7 IMPORTANT
  • If the measured angle deviation has a positive sign, the signal arrives from the camshaft Hall sensor too soon. To remedy this, the camshaft must be rotated to delayed.
  • Check timing.
