good morning and happy new year to all
recently i have been getting fallowing codes. however engine warms as it should, does not overheat, and cools down as it should.
the O2 codes I am very confused about and cannot find a solution for/ i have a 3inch down pipe with no cat, and in order for the 2nd post cat o2 sensor to fit i had to run a 90 degree adapter. now due to adapter every once in a while i will get a fault code for the post cat B1S2 code such as one listed below. but now i am getting a 2nd o2 sensor code for B1s1 sensor and i do not understand why the code says too Rich?
Mode 03: Emission related fault codes
Address 7E8: 3 Faults Found:
P0137 - Oxygen (Lambda) Sensor B1 S2: Signal too Low
P2196 - Oxygen (Lambda) Sensor B1 S1: Signal too High (Rich) how could signal be to High??
P2181 - Performance Malfunction in Cooling System
