Codes: P0135 P0155 P0159
Hey guys,
I don't know if this is related but ever since I was messing around with the starter relay and swapping them with the ones next to it, I'm now getting these codes: P0135 P0155 P0159
P0135
A/F Sensor 1 heater system malfunction probable cause
1. - Open or short circuit condition
2. - Poor Electrical Connection
3. - Faulty A/F Sensor 1
P0155
A/F Sensor 21 heater system malfunction probable cause
1. - Open or short circuit condition
2. - Poor Electrical Connection
3. - Faulty A/F Sensor 1
P0159
Secondary H02S22 (Heated oxygen sensor - Bank 2 Sensor 2) circuit slow response probable cause
1. - A/F ratio concern
2. - Blocked exhaust
3. - Faulty H02S22 (Bank 2 Sensor 2)
The following relays were swapped around:
ACC - Accessory Power Socket Relay;
ST CUT - Starter Cut Relay;
LAF - Air Fuel Ratio Sensor Relay;
P/W - Power Window Relay.
So maybe I screwed something up with the Air Fuel Ratio Sensor.
Note: The check engine actually comes on and then next trip it's off again.
If you guys can help me out.
