Good evening chaps!

yesterday my emissions warning light came on my dashboard, I have done the pedal test which came out with code 0136 which is Oxygen O2 Sensor Circuit Low Voltage (Bank 1, Sensor 2) I have spoken to a garage who has told me (without looking at it) that I need a new sensor, he has quoted me £25 for the sensor and £25 for the labour. Not a lot of money I know but when you're as skint as me! Haha!

my question is this, is it okay to wait 3 weeks till pay day or is this a big issue that could cause more damage?

Also what are your thoughts on the price quoted?

thanks in advanced comrades!

£25 for the sensor would mean they are fitting a non-genuine part. These sensors are often not to OE spec and can cause more problems than they are trying to solve.

Also, I would be wary of a garage that offers a fix without even looking at the car. How do they know the sensor is at fault?

Shouldn't be a problem driving the car in the mean time. The second sensor only confirms how efficiently the catalyst is working - it has no bearing upon the engine fuelling.

I had this exact fault on my 1.4 Tigra, something to maybe bare in mind...

The 'bank 1 sensor 2' O2 sensor was replaced (the one measuring emissions) and the light came back on a few miles after it was replaced... Was infact another O2 sensor that was faulty but not bringing up it's own ECN... The Emissons O2 sensor was picking up the fault through emissions hence ECN 0136 for the emissions O2 sensor, and why it's being replaced had little effect...

I think you should have proper diagnostics to save yourself time and potentially money :)
