Fault Codes help!

[RoverAndy]

My 2000 Discovery II is getting the following fault codes:

P 0733 Gear 3 Incorrect Ratio
P 1300
P 0308 Cylinder 8 Misfire Detected
P 0306 Cylinder 6 Misfire Detected
P 0302 Cylinder 2 Misfire Detected
P 0171 System Too Lean (Bank 1)
P 0174 System Too Lean (Bank 2)
P 0300 Random/Multiple Cylinder Misfire Detected
P 0308 Cylinder 8 Misfire Detected
P 0304 Cylinder 4 Misfire Detected
P 0306 Cylinder 6 Misfire Detected
P 0302 Cylinder 2 Misfire Detected

First, does anyone know what P1300 means? Second, any ideas on what to replace to fix the problem? I just replaced the driver-side front O2 sensor yesterday.

Thanks!

Here are two places to start.

Next time try a Google search. It is faster that waiting for a reply.

P 1300 Catalyst damaging misfire multiple cylindersDrive cycle C:Signal out of range - above maximum

This is what that code means

Retelling Of The Problem

I am going to retell my problem. Hopefully the added information will spark some ideas.

My 2000 Land Rover Discovery II's engine light came on. I got it checked, and these were the following codes:

P 0134 O2 Circuit No Activity Detected (Bank 1, Sensor 1)
P 0134 O2 Circuit No Activity Detected (Bank 1, Sensor 1)
P 0171 System Too Lean (Bank 1)
P 0174 System Too Lean (Bank 2)
P 0300 Random/Multiple Cylinder Misfire Detected
P 0301 Misfire Cylinder 1
P 0303 Misfire Cylinder 3
P 0303 Misfire Cylinder 3
P 0305 Misfire Cylinder 5
P 0305 Misfire Cylinder 5
P 0307 Misfire Cylinder 7
P 0307 Misfire Cylinder 7
P 0733 Gear 3 Incorrect Ratio
P 1174 Lambda control adaption fault bank 2.Last occurrence - maximum signal
P 1300 Catalyst damaging misfire multiple cylindersDrive cycle C:Signal out of range -
above maximum

So, we came to the conclusion that the O2 sensor was bad, and that it was probably causing all of these problems. Thus, we replaced the front-driver's side sensor. Unfortunately, soon thereafter, the light came back on, this time with these problems:

P 0171 System Too Lean (Bank 1)
P 0174 System Too Lean (Bank 2)
P 0300 Random/Multiple Cylinder Misfire Detected
P 0302 Misfire Cylinder 2
P 0302 Misfire Cylinder 2
P 0304 Misfire Cylinder 4
P 0306 Misfire Cylinder 6
P 0306 Misfire Cylinder 6
P 0308 Misfire Cylinder 8
P 0308 Misfire Cylinder 8
P 0733 Gear 3 Incorrect Ratio
P 1300 Catalyst damaging misfire multiple cylindersDrive cycle C:Signal out of range - above maximum

Does anyone have ANY idea as to what could possibly be triggering these errors? Did I replace the wrong sensor? Is there just another sensor that is probably bad also? Anything, just please help!!

Thanks!

CHECK THE AIR FILTER BOX THE LID IS PROBABLY NOT INSTALLED CORRECTLY IF THE AIR BOX HAS ANY BROKEN OFF TABS THAT LINE UP THE UPPER AND LOWER PARTS OF THE AIR BOX OR THE PLASTIC HOUSING IS WARPED THE WHOLE AIR BOX NEEDS TO BE REPLACED ,IT WILL COME WITH A NEW AIR FILTER INSIDE IT . ALSO THE P0171,174 ,PO733 IS DIRECTLY RELATED TO THE AIR BOX PROBLEM AND YOU WILL ALSO NEED A MASS AIR FLOW METER .
AS FOR THE MISFIRE CODES YOU SHOULD CK. SPARK AT THOSE PLUG WIRES YOU PROBABLY FIND THAT THE SPARK IS INTERMINTANT, IF SO YOU WILL NEED NEW PLUG WIRES AND COIL PACKS. WHILE YOUR IN THERE YOU MIGHT AS WELL PUT IN NEW SPARK PLUGS
GOOD LUCK !!!

 

[RoverAndy]

Thanks greendisco! I will check all of that and get back to you. Also, do you know roundabout how much all of that costs?

Thanks!

codes

Are the (too lean) codes directly related to the airbox? I thought it could be a whole heep of problems like a faulty hose or an O2 sensor?

 

[Gordo]

whats up

Andy, your retelling of your problem confuses me but its late. First it is all even numbers one version and then all odd in the other. I would start simple if it was mine. Check to be sure your intake manifold isnt coming loose causing a vacuum leak. Pull one plug wire at a time to see if it is missing on a side or cylinder. Pull the plugs and read the color of them too. I had a loose manifold problem on a recent rangie I bought but never read the codes. It also had a bad ECU causing it to run badly on one bank which was obvious once I pulled the plugs (the injector harness had a couple shreaded wires that were shorting out and burned the ECU). These problems can be difficult at first to figure out. A Vacuum test might be a good idea too to be sure you dont have a clogged cat or something. I wouldnt start throwing parts at it. Gordo

 

[RoverAndy]

The codes that I listed are 100% correct. I have NO IDEA why after installing the 02 sensor that the cylinder misses switched sides. It is very weird. But on the bright side, it did fix the faulty O2 sensor problem, haha.

If anyone else has any more ideas, or other things to check, PLEASE let me know! I plan on looking it over this weekend.

Thanks,

ANDY

try cleaning your mass air flow sensor with some electrical contact cleaner. i had similar codes and that seemed to fix the problem.

 

[brianpack01]

Cleaner

The cleaner is avaliable at Lowes for around 5.90 or so.

 

[brianpack01]

for the record....

Just for the record...I had a too lean (banks 1 and 2) fault codes.....all I did to solve it was to shoot the MAF with a little cleaner. Wa la! As of now, the light is off and the engine runs ok. Is running a thicker oil safe for the sake of eliminating a little knocking with the engine?

Bringing Closure to Fault Code Problem

Instead of trying to figure out what the problem was using a trial-and-error process, I decided to go ahead and take it to the dealer. I took it to Land Rover Birmingham (Alabama).


SYMPTOMS:
You can see a listing of the fault codes in my previous posts. Overall, my Discovery was not running efficiently (with fuel), had a huge loss of power (felt like 4 cylinder, not a V8; couldn't pull even the smallest hills well), and was missing.

This is a list of what Land Rover Birmingham did:
1. Replaced Mass Air Flow Meter
2. Replaced Air Filter
3. Replaced Spark Plugs

They said that if the light came on again with the same misfire codes, then it would need a valve job.


OUTCOME:
The light never came back on, and my Discovery runs great! It is amazing how much a difference fixing the problem made. Now my Discovery is back to full power, and that is a beautful thing!

That was the best $688.36 that my parents ever spent!


LAND ROVER BIRMINGHAM:
If you live in Alabama and need you Land Rover worked on, take it to Land Rover Birmingham. First, there dealership is awesome. Second, they are experts on fixing Rovers. And third, service is great. I called on Friday, made an appointment for Monday, and had my Discovery back by Monday night. I know where I'll take my Rover or buy my Rovers in the future!

If you'd prefer an independent shop, Boddiford's is up the road in Mobile. Matt and Frank are good folks.

Andy,
I'm glad you got your Rover fixed! However, it would have been interesting to fix one of these things at a time to see which was the real problem. My money would be on the MAF.

 

[RoverAndy]

The Reason

Well, the reason that all of these things were fixed at once was twofold:

1. I live an hour away from Birmingham in Tuscaloosa (attend the University of Alabama), and can't very easily keep bringing the Discovery back to the dealer. By fixing all of these things, it basically eliminated all possibilities except that it needed a valve job.

2. It was time for a tune up anyways. Plus, replacing the spark plugs and air filter really added little to the cost, and taking time out to travel back and forth would have been much more costly.

I hope this thread helps out anyone that experiences these same types of problems.

Hmm. This same repair was done for me back in February by LandRover Portland, and is why I will never set foot in there again. They charged a reasonable amount for the MAF, ($137.00) the total was $628.23. Of that labor was $462.24.

I'm sorry, but even at $100/hr- it shouldn't cost that much to pull codes, replace 1 ignition wire and replace a MAF. My total bill that day was over $1500.00. (60K service, front brake pads and the afforementioned heist.)

Thankfully I haven't had any problems since- if anyone in the Portland area could recommend an independant shop they're happy with, I'm all ears.

Hey Andy you know my buddy Jesse Mccarty. He has the 2000 DII down there.
