mc Posted October 7, 2011 Share Posted October 7, 2011 Today I got my first CEL appear. I read the codes using the flashing light method, and got the following: P0139 O2 Sensor Circuit Slow Response (Bank 1 Sensor 2) I'm assuming that 10 slow flashes after that code mean its the only code that is current, and the ones after are old stored codes? I think the next codes were P0159 O2 Sensor Circuit Slow Response (Bank 2 Sensor 2) P0146 O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 3) P0166 O2 Sensor Circuit No Activity Detected (Bank 2 Sensor 3) P0147 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 3) P0167 O2 Sensor Heater Circuit Malfunction (Bank 2 Sensor 3) then the 10 slow flashes again. So I might be jumping to a conclusion here, but these would be due to having the Berk HFC's fitted 500 miles ago? Would they have been caused by disconnecting the lambda sensors, or do I need the spacers from Zmanalex? (I thought it was only decats that needed these?) And lastly, could I cause damage by driving with the check engine light on, if it comes back? Cheers Mike Quote Link to comment Share on other sites More sharing options...
spursmaddave Posted October 7, 2011 Share Posted October 7, 2011 Very common fault after having Berks fitted... wont cause damage but could if the light comes on for a different reason and you ignore it.... Choices - Put up with the light Learn the reset procedure Spacers from Alex UpRev Quote Link to comment Share on other sites More sharing options...
mc Posted October 7, 2011 Author Share Posted October 7, 2011 ah ok, not so worried now, thanks. I did reset the codes so will see what comes up next time. so as I am planning on getting the UpRev now that mods are complete, will I not require the spacers? if the lambda's aren't functioning correctly, doesn't that mean that the AFR will be wrong? could be running lean?

spursmaddave Posted October 7, 2011 Share Posted October 7, 2011 No spacers required if you get the uprev, just make sure you ask them to sort it out when you take the car in... Not sure about all the technical stuff, but ive had no problems whatsoever Quote Link to comment Share on other sites More sharing options...
