ecousi Posted April 4, 2013 Share Posted April 4, 2013 HI everyone thanks for looking at my post, My engine light is doing my head in!! it has been in to a Nissan dealer to have the fault code read and diagnosis but we are not getting anywhere. Has anybody else had this code P0430 TW Catalyst SYS-B2. The first time the light came on the code was P0420 TW Catalyst SYS-B1 (drivers side bank) so the dealer advised replacement of the rear 02 sensor on that side. This was completed and for a while the light was off, however now every time I do any motor-way driving Constant speed around 3000 RPM the light comes back on and the SyS - B2 fault code is displayed. the light does not go out with restarting the engine but is on all the time until I go into the dealer to have it turned off. Can anyone help?? I have a feeling that one of or both the cats are at fault but with new cats at £1500 each dont want to make a very expensive mistake, (the dealer has advised that the cats need to be replaced and then possible further testing) I am also concerned that this fault may be with the engine and may just knacker new cats in a short space of time. Any thoughts or ideas welcome!! Sorry forgot to add the engine is running fine with no hesitation or missfire. Thanks for reading Ed Quote Link to comment Share on other sites More sharing options...
glrnet Posted April 4, 2013 Share Posted April 4, 2013 You'll pick up a set of cats on here for a lot less than that. Quote Link to comment Share on other sites More sharing options...

ecousi Posted April 4, 2013 Author Share Posted April 4, 2013 Hi Darren b sounds good. Will the HFCs cause the mil light to come on? Quote Link to comment Share on other sites More sharing options...
Keyser Posted April 4, 2013 Share Posted April 4, 2013 You will need O2 spacers to stop the warning light with the Berks about £20. And along Quote Link to comment Share on other sites More sharing options...

Sam Mcgoo Posted April 5, 2013 Share Posted April 5, 2013 The cats/o2 sensors could be on the way out, but this is a fairly common problem especially when it is very cold. It is not a code that will do any harm to your engine, so don't worry about that. You can read / reset the codes yourself to save yourself some cash. 1. Buy yourself a cheap OBD2 reader from ebay (about £20) or a bluetooth one and get an app for your android phone called 'Torque' (I think there is a similar Apple app) 2. Do the 'Peddle dance' as follows: Confirm that accelerator pedal is fully released, turn ignition switch “ON†and wait 3 seconds. Repeat the following two procedures quickly five times within 5 seconds: Fully depress the accelerator pedal (HARD). Fully release the accelerator pedal. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the CEL starts blinking. Fully release the accelerator pedal (while the CEL is still blinking) Wait about 10 seconds. - Count the flashing lights now- this is the code. Fully depress the accelerator pedal and keep it for more than 10 seconds. Fully release the accelerator pedal (The CEL light will continue to blink). Turn ignition switch to “OFF†position and now you can start the car. The CEL light should be gone. There is a full guide in the guides section on here. If you want to try oem cats, PM zmanalex as I'm sure he'll have some good used ones for a good price. Or, use it as an excuse to buy the HFC and get a uprev to reap the benefits.

dave_c Posted April 21, 2013 Share Posted April 21, 2013 You could just get a code reader and turn it off every now and again Quote Link to comment Share on other sites More sharing options...
