Camshaft Hall sensor (B6/2, B6/3) | ||
1 | Fault code ( Readout on generic scan tool) | P201A Camshaft Hall sensor for right bank of cylinders (B6/3) (P0341) P20B8 Camshaft Hall sensor for left bank of cylinders (B6/2) (P0340) |
2 | Fault storage Actuation of engine diagnosis indicator lamp (EURO4) or CHECK ENGINE (MIL) malfunction indicator lamp | after expiry of test duration and fault following two successive driving cycles with faults |
3 | Checking frequency | Continuous |
4 | Checked signal or status | Camshaft Hall sensor signal |
5 | Plausibility No signal Quantity |
The signal must change from 0 to 1 and from 1 to 0 within 2 engine revolutions, max. of 1 signal change per engine rotation |
6 | Check prerequisites | - engine speed 25 to 6000 rpm - no fault in crankshaft position sensor |
7 | | If the signal from a camshaft Hall sensor is missing or if false synchronization is recognized, fuel cutoff will occur to avoid damaging the TWC. |
