The signal of the oxygen sensor upstream of the catalytic converter of the right cylinder bank is shifted towards 'Lean'. (P2A00)
Possible cause:
- The signal of the oxygen sensor upstream of the catalytic converter of the right cylinder bank is shifted towards 'Lean'.
Affected functions:
- Engine diagnosis
- Exhaust system
-------------------------------------------------
Test 1: Check exhaust system for leaks.
Test 2: Check component G3/4 (Right O2 sensor, before TWC [KAT]).
Test 3: Check component G3/6 (Right O2 sensor, after TWC [KAT]).
1. Check exhaust system for leaks.
Warning!Communication with ECU required.
2. Check component G3/4 (Right O2 sensor, before TWC [KAT]).
Warning!Communication with ECU required.
3. Check component G3/6 (Right O2 sensor, after TWC [KAT]).
Warning!Communication with ECU required.
