Code Help
 
Just finished reinstalling the drivers side exhaust manifold and completed the Tune-up, Plugs and Wires, Now I have a code I do not recognize.

P0130-from the exhaust leak, I believe the new O2 needs to be replace again.
P0135- same as above
P0171-same as above

P1129-Nevermind, I found it. Man My search skill are off today.

Also the #2 plug had been installed just over half way, Champion plugs no Idea how long they were in there, I ran a Thread cleaner through and installed the new plug.

It runs way better now. Just have the one code I need help with.

P0130 O2 sensor circuit malfunction (bank 1, sensor 1)
Front sensor LH bank stoichiometric ratio outside operating band

P0135 O2 sensor heater circuit malfunction (bank 1, sensor 1)
Front sensor heater LH bank - short/open circuit

P0171 System too lean (bank 1) Multiplication injector adaptive fuelling - lean limit
exceeded LH bank

P1129 O2 sensors swapped bank to bank (sensor 1) Front sensors transposed

May want to deal with 1129 first, and see if condition clears

How would the sensors switch? This is the first Time this code has come up, I have been getting the others regularly because of the exhaust leak.

Savannah Buzz 05-09-2012 09:49 PM

If you have not moved wires, then it is most likely a phantom ghost code brought on by the other one O2 sensor. Seems like that sensor needs some connector attention or maybe replacement.

Kalel 05-09-2012 10:18 PM

Under Warranty. I will be removing it tomorrow and replacing it. Hope it works.

Kalel 05-11-2012 04:48 PM

Replaced the O2 and cleared the codes, drove it around for a while. MiL is still off. Also had a shop clear the amigos again. Last time I went off road, everything worked great, even the Traction Control. Stopped for lunch and the 3 Amigos Came on, all I could think of was that the ABS sensors had got some dirt on them.

Kalel 05-29-2012 11:04 PM

And the MIL light is back on, P0130 is the only code.

Kalel 05-30-2012 09:12 PM

Anyone have any ideas as to what this could be? It is a Bosch 02, 3rd one as I thought that I burned one up and then maybe got a defective one. I have checked the connector and it is plugged all the the way in.

1 Attachment(s)
See attached from Bosch manual, it shows voltages that generate that code. Connector problems?

Kalel 05-30-2012 10:46 PM

Thanks, I will test them. Is there a Scanner or di I need to use a Volt/ohm meter?

Savannah Buzz 05-31-2012 04:17 AM

Most live data scanners will show volts from O2s out to three decimal places, some cheap meters don't go that far. So the answer is either, but both are handy to own. And this may be a good excuse to buy an Ultra Gauge.

Might also inspect the wire harness for damage as well as the connection for oil or dirt.
Have you been going thru a lot of oil or coolant on bank 1 that could be contaminating that 02?

Kalel 05-31-2012 08:52 AM

It did have oil leaking on that side. Would cleaning out work? I could try that while I get a hold of a good scanner.

Disco Mike 05-31-2012 10:02 AM

You won't know till you clean it but the leaking v/c gasket will allow oil to get on the connection and mess with your 02.

Kalel 05-31-2012 12:06 PM

Oil leak has been fixed, I have a buddy with a Hawkeye scanner and he is coming over to help out.

Disco Mike 06-01-2012 09:29 AM

Did you clean the 02 connections with electric contact cleaner?

Kalel 06-01-2012 12:47 PM

Not yet, my father in law, who is 86, fell and broke his ankle. I have been dealing with that, as a stay at home dad, but my buddy will be here today and I can get to work on it.

Kalel 06-01-2012 07:06 PM

The readings are odd. It starts up and has voltage, then it reads 0 volts and % and open. Bank 2 shows proper numbers and closed. Now when you rev the engine the numbers go back up, back to idle the numbers go to 0. He is coming back next week to do a point to point test to check the connector and wiring.
