So I just bought a used 2000 LR discovery with 95,000 miles on it. It came with the "3 amigos" on and was told they had it looked it and it was a wheel sensor. Today the SES light came on and had Advance Auto Parts lookup the codes for me. It had 9 codes--all look like emissions to me but wanted someone else's opinion.Here they are:
P0734
P0741 -Torque Converter Clutch Solenoid Circuit Performance Or Stuck Of
P0733
P1590
P0174
P0171
P0154
P1535
P0722

Perhaps the MAF and o2? It seems to take a long time to shift as I get up speed(Possibly the P0734). The car runs fine, not missing or stuttering. Brakes are starting to squeak at low speeds. Besides from that, nothing feels out of the ordinary.

Thanks for your time.
Brad

 

You need a new MAF sensor.
The 1590 is a ABS fault.
Replace the MAF and clear the lights before you do anything else to the truck.

 

Thanks Spike. I have read all the forums I could, and that seemed to be the cause. There were some people who thought it was a tranny issue. I just took a look at the air filter and it was pretty dirty(loose debris). You weren't kidding when you said money pit.
On a positive note, by dropping a screw down the front of the vehicle, I took a better look at the front propeller shaft and it has the after market u-joints with the grease fittings on it.
Any suggestions on where to purchase a MAF sensor?
Thanks again.

Also check e-bay and Craigs list, just becareful when buying off of them as you may not get the right one.

 

Thanks again. You have been a big help.

 

Only replace the MAF for starters then get the codes cleared, see what shows up and get back to us.

 

turned out it was the MAF and the tranny. The tranny had a crack in it, plus the head gaskets are leaking. This is had been an interesting couple of weeks.
2500=tranny rebuild and heliarch the case
1500=for head gaskets
also the master cylinder started leaking(not the booster thank god)
and the head liner started to fall.

9000 total into it and no turning back now--I will have to drive it till the wheels come off.

 

You can do the head gaskets yourself and save yourself a grand.

 

i thought about it, but I do not have all the tools that i would need. Plus i am moving so do not have much time--Bad timing
