Originaly got these CEL codes.
16805 - Warm Up Catalyst; Bank 1: Efficiency Below Threshold
P0421 - 001 - Upper Limit Exceeded - MIL ON
16815 - Warm Up Catalyst; Bank 2: Efficiency Below Threshold
P0431 - 001 - Upper Limit Exceeded - MIL ON
Replaced both the CATS and now I get these CEL codes.
17526 - Oxygen (Lambda) Sensor Heating; B1 S2: Open Circuit
P1118 - 004 - No Signal/Communication - MIL ON
17522 - Oxygen (Lambda) Sensor; B1 S2: Internal Resistance too High
P1114 - 004 - No Signal/Communication - MIL ON
16537 - Oxygen (Lambda) Sensor B2 S1: Response too Slow
P0153 - 002 - Lower Limit Exceeded - MIL ON
Its like WTF.
Someone said there was a fuse to the O2 Sensors that goes bad.
Never heard that before.
Any thoughts on the problem?
I am going to replace the 3 sensors that are showing bad.
In the end this is getting coded out. You know who’s tune.
