Hi I have a V70 99 with the check engine light on. It has the code P0135 (OBD Reader) And also when I put the brake the bult out warning came on. I checked all the lights and they work fine. Whats the problem?



Please help me...

 

You still have one brake bulb out or the connection is bad or dirty (common)
I have no idea what that code is, what does it say?

 

Thank you,

the code says (O 2 sensor heater circuit malfunction; Bank 1 Sensor 1)

 

O2 sensor is bad.

 

Thank you, I will buy a new sensor.

 

Make sure it is OEM or atleast a Bosch with the plug. Or if it is a Non-turbo Denso setup buy a Denso sensor.

 

Ok , thank you so much...
