So now I'm officially stumped. I replace both pre cat O2 sensors, then the MAF sensor and am still getting the P0130 code. What else could I be looking at for this, plugs and wires?

HELP!

 

i believe certain emission parts have to be installed for a while before they will clear from the memory. have you put 50 miles or more on it since they were replaced>

 

The O2 sensors yes, I drove it 100 miles before going ahead with replacing the MAF to see if the code would go away. I haven't driven it 50 since installing the MAF though. I'll post back after tomorrow as I will have driven over 50 then.

Thanks

 

I have about 80 miles on it since installing the MAF and am now getting a 130 and 0171 code on the Ultra Gauge. It doesn't seem as if the ECU has reset itself. Any other suggestions on what to do at this point?

 

Pull the battery terminals, let the capacitors in the truck drain and reconnect. This will do a hard reset of the ecu.

 

Did you actually clear the codes? They don't go away by themselves.

 

I just did the same thing and this had me stumped for about 3 months with this P0130 code, getting terrible gas mileage. Make certain you clean the drivers side front 02 (female) connector very well. Look up in female connector and see if there is green corrosion. Spray it with electric contact cleaner. Use Qtips to get up in there. You could also have a NEW bad 02 sensor. Swap one out. p0130 means bank 1 which is your drivers side on the fuel rail. I had to search landroversonly.com for a lot of this, since it seems our site is lacking on definitive answers on the issue. Where is Spike & DiscoM when you need them?

 

Good question. I have not seen Mike make as many appearances on here as of late. Spike is still here I believe but I think he is probably getting ready to move on. He mentioned selling his Disco on facebook and upgrading to a newer Range Rover so who knows. But yes this dam code seems to be a gremline and ironically it resurrected on my truck on my way home tonight after nearly a month of no trouble codes. It literally just comes then goes for awhile. Ive spent a couple hours researching the code and even tried the cigar smoke test but no luck finding the problem yet. I just clear the codes and drive on.

 

Engine Code: p0130

Land Rover Engine Code: P0130 = O2 = sensor circuit malfunction (bank 1, sensor 1) Front sensor LH bank stoichiometric ratio outside operating band.

Bank 1 is driver's side in the USA.
You put in a crap or junk O2 sensor or you got a dud.

Put in a brand new Bosch and try again.

 

Also - check the manifold bolts are tight on the manifolds.
Listen carefully for exhaust leaks and correct them.

And if you have sprayed crap cleaner into the MAF trying to clean the MAF with the engine running then this can LUNCH your O2 sensors too.
