Hi,

My "check engine" light is on, the code says it:

P0153 O2 Sensor Circuit Slow Response (Bank 2 Sensor 1)

P0155 O2 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1)

How can I take care of this problem?

Thanks.

A code P0153 may mean that one or more of the following has happened:

The oxygen sensor is faulty
The wiring to the sensor is broken / frayed
There is an exhaust leak

P0155 B2S1 heater oxygen circuit-check as above

So, what should I do?

1. Replace the oxygen sensor.
2. Replace the wire to the sensor...

BTW, the light turned on after I have an auto-accident which required the replacement of the car hood.

Thank.

Inspect the wires to it-if okay either you replace the sensors or bring it in to the professionals so they can determine if its the sensor/wire or computer problem-
