danZman Posted September 22, 2009 Share Posted September 22, 2009 Ok, My car has a cel reading P0037. This is supposed to be bank 1 sensor 2 failure. I have spent best part of £500 quid getting it diagnosed, replacing the CAT and sensor (because the sensor was stuck in the cat) and getting it all fitted. Got it fitted yesterday, went home, performed the CEL light clearer thingy (by pressing the pedals) and it was gone. Went on a 20 mile drive and it didnt come back. This morning, started the car, bang, straight away it was back. Are the sensors really required? Alot of exhausts come with de-cats, surely it doesn't effect your fuel / air ratio that much if people use these things for years and years. I have no idea what to try next. Help!

ZMANALEX Posted September 22, 2009 Share Posted September 22, 2009 Dan, Code P0037 is a Generic DTC Definition for: Heated 02 Sensor Heater Control Circuit Low (Bank 1 Sensor 2) Clear the code again and try an ECU reset. Quote Link to comment Share on other sites More sharing options...
danZman Posted September 22, 2009 Author Share Posted September 22, 2009 Alex, Do you mean clear the cel code by pressing the pedals as well as resetting the battery for 30 minutes? Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted September 22, 2009 Share Posted September 22, 2009 ECU reset not battery disconnect, the battery disconnect won't gaurentee ECU reset. if its the lamda sensors, an anti fouler might cure the issue. Quote Link to comment Share on other sites More sharing options...

Oh ok, in that case I have already performed the ECU reset. I have anti fouler already in place for this sensor. Still have the problem.

rtbiscuit Posted September 22, 2009 Share Posted September 22, 2009 whats your location? someone with an OBDII reader might be able to read your code and make sure it is what you think it is. i struggle to read the flashes. might also be worth checking to maske sure its the same issue. might be a new error?

danZman Posted September 22, 2009 Author Share Posted September 22, 2009 I am in sittingbourne, which is North Kent. I did try purchasing a ODB2 reader but the bloke that sold it to me lied and said it read JOBD when it didnt. If anyone is local and has one to hand I would be appreciative.

danZman Posted September 22, 2009 Author Share Posted September 22, 2009 Afraid so, makes things even more difficult. When I said I installed a anti-fouler, i meant sensor spacers, I dont know if there is a difference between the 2. Quote Link to comment Share on other sites More sharing options...

jerry3167 Posted September 22, 2009 Share Posted September 22, 2009 This is the same problem I had, and as of this week still have Nissan have done the following under my 2 year warranty: They have consulted Nissan UK and now they have ordered a brand new ECU for me..@£1300+vat!!! Brand new front sensors@ £144 each Spacers for the rear sensors ECU reset icl ecu learning Numerous testing, all of which shows the parts to be working correctly, all DTC ok and no fault. But now not even driving at speed will trigger this error, something as simple as reversing out of my drive or pulling away from a parking space will set it off!! I have High flow cats 5zigen exhaust Plenum spacer Quote Link to comment Share on other sites More sharing options...

I have High flow cats 5zigen exhaust Plenum spacer Christ..... That must have cost a few bob for them! Its not good to hear this, sounds like im gonna be fighting forever to get my ecu light to go out. Im half tempted to install 2 electronic O2 sensor simulators for the rear sensors and be done with it. Apparently only the front 2 sensors determine the fuel / air ratio and have any effect on your engine. In which Nissan fed me a load of Bolo**s saying I needed to get mine fixed quickly to prevent engine damage. If all the rear sensors do is tell you if your saving the environment or not. I'm not interested in spending serious money on it. Quote Link to comment Share on other sites More sharing options...
