The O2 Sensors makes sense as I am getting the "Antipollution fault" when the car is started. Anyone know of what the other stuff is.
#2: Re: Diagnostic Results Author: Deckchair5, Location: Bath UKPosted: Sun Apr 07, 2013 5:33 am ---- I would check out and fix/change the O2 sensor as it's obviously causing problems and you may well see the other codes disappear as fuel trims will be excessive and flagged (P0170) and you are experiencing misfires which is to be expected when the ECU has no idea what is happening in the exhaust Last edited by Deckchair5 on Sun Apr 07, 2013 12:37 pm; edited 1 time in total
#3: Re: Diagnostic Results Author: xdoddyx, Location: NewcastlePosted: Sun Apr 07, 2013 9:58 am ---- Taken from Peugeot Central:
P0170 means there was a malfunction in the ECU's control of the air:fuel ratio.
Fuel saturated engine oil
Possibly bad O2 sensor
(Oil contamination in MAF connector or O2 sensor connectors. Also check ignition coils, cam and crank sensors.
Defective MAF
P1337 - Faulty Crankshaft Sensor, which could also be flagging up the P0170.
P0132 - A code P0132 may mean that one or more of the following has happened: The oxygen sensor heater circuit is shorted out The wiring to the sensor is broken / frayed
P0131 - A code P0131 may mean that one or more of the following has happened: Faulty o2 oxygen sensor Short to voltage on O2 signal circuit High resistance or open on O2 signal circuit.
Replace the Lambda sensors, and get the codes wiped, see if that takes any of the codes away.
If the P1337 and P0170 still remain, do a test on the coil pack, aswell as the crank sensor.

The P0170 excessive fuel trim is no surprise when the precat O2 sensor is malfunctioning
#5: Re: Diagnostic Results Author: IceWhyte, Posted: Sun Apr 07, 2013 2:52 pm ---- So would this bad lambda sensor usually cause a lack of power? I have just got the car so no sure what to expect.
Also, is there a method of checking if the sensor is faulty before buying a new one?

The lambda is to help ECU trim for maximum economy under steady throttle conditions so without it the car will have bad fuel consumption
is there a method of checking if the sensor is faulty before buying a new one?
Sure, but it depends on your equipment and capabilities. click here
#7: Re: Diagnostic Results Author: IceWhyte, Posted: Sun Apr 07, 2013 4:09 pm ---- Don't laugh but I read on several forums that when they get this fault they go to the BP garage and put £20 of that Ultimate fuel in and it sometimes clears it. You think there is any truth in this?
#8: Re: Diagnostic Results Author: Deckchair5, Location: Bath UKPosted: Sun Apr 07, 2013 4:25 pm ---- Ha! Can't see that curing a bad O2 sensor if that's what you have. If you're unable to test the O2 sensor circuit then I would just put a new precat O2 sensor in there as they're not that expensive and your car is stating it's not happy at all with the present one's output
They don't last forever and have a pretty tough life in the heat and vibration of the exhaust Last edited by Deckchair5 on Sun Apr 07, 2013 4:50 pm; edited 1 time in total
#9: Re: Diagnostic Results Author: IceWhyte, Posted: Sun Apr 07, 2013 4:37 pm ---- Ok thanks.
I have searched eBay for 02 sensors and find plenty but they don't say if they are pre cat, how do I know if its the right one?
Also, is it best to get a branded one or will a cheap one do the job? There is a huge range in prices.
#10: Re: Diagnostic Results Author: Deckchair5, Location: Bath UKPosted: Sun Apr 07, 2013 4:53 pm ---- Branded one will always be less hassle as they are dealing with very small voltages of less than 1v
Look in Servicebox click here to get your sensor type ref number for your vehicle and then you know you are getting the right one
#11: Re: Diagnostic Results Author: IceWhyte, Posted: Mon Apr 08, 2013 4:07 am ---- Thanks very much. You have been a great help. Same to other members who posted here.
#12: Re: Diagnostic Results Author: IceWhyte, Posted: Mon Apr 08, 2013 5:21 am ---- Anyone ever heard of Volz Autoteile? They have the sensors for £20-£30. Should I just play it safe and get an NGK one for £60?
#13: Re: Diagnostic Results Author: Deckchair5, Location: Bath UKPosted: Mon Apr 08, 2013 6:34 am ---- Are you looking on Ebay? You can normally get a proper Peugeot model dedicated O2 sensor with the right connector, delivered for under £30. You don't need to go mad with prices but you do want one that is intended for your vehicle
#14: Re: Diagnostic Results Author: IceWhyte, Posted: Mon Apr 08, 2013 7:01 am ---- Yeah it is eBay I am looking on.
#15: Re: Diagnostic Results Author: Deckchair5, Location: Bath UKPosted: Mon Apr 08, 2013 10:18 am ---- Way to go then
