Error code 27 - sub oxygen sensor

Recommended Posts

Checking the diagnostic codes for something else also revealed an error code 27, sub oxygen sensor. Anyone have any advice for working out whats wrong or is it likely to be the sensor that needs replacing? The car has over 200k miles on it so I'm anticipating sensors like this are reaching the end of their life.

 

Is this an easy sensor to replace and any clues on the sort of price?

Hi did you manage to fix code 27 error as I have the same problem .The car turns over but not starting i ve been told the sub ox ygen sensor would not stop it starting so more ikeley connection from ECU.

 

Check your igniter bracket near the LH turret in the engine bay. When they get rusty or painted the car turns but wont fire as they act as an earth
