P0130 & P0135?

[Simon_16v]

Hey Guys,

At the weekend I had a new centre section and my decat taken off. As soon as I drove off the car really wasn't happy, felt like it was misfiring and really holding back. I left it for a couple of minutes and it seemed to go away and on the drive home the car ran fine.

Finally got my mate to clear the fault codes from having the decat on and thought that would be the end to the EML.

Since Sunday the EML keeps coming back on and whilst the engine is cold or on choke the car sounds like it's misfiring again and wanting to stall.

P0130 - O2 Sensor Circuit
P0135 - O2 Sensor Heater Circuit

Those fault codes both keep coming up each time the EML comes on.

Any ideas on what it could be? I hope it isn't the cat that needs replacing .

Thanks!

Is this the pre-cat lambda sensor?

I know that P130 is the front sensor (Before Cat)

Is it worth switching them around?

 

[Simon_16v]

Anyone?

I just changed mine for a new one but you can try and just swap them around it you wish

P0130 - O2 Sensor Circuit Bank 1 Sensor 1

P0135 - O2 Sensor Heater Circuit Malfunction Bank 1 Sensor 1 Both codes relate to pre-cat sensor.

Sweet, well this morning there was no EML light like normal so maybe the redex is cleaning it up a bit?

Either way as soon as it crops it's ugly face up I will be getting a Bosch pre-cat sensor.
