Hi everybody, newbie here - Looking at an '02 D2!

Looks like there are some codes that might be resolved if the MAF is cleaned/replaced and some hoses checked, but there's one code I'm not able to figure out. Anybody run into p1773 before?

The other codes are: P1884, p0103, p0112, p1415, p1412.
Excited at maybe getting my first disco but don't want to jump the gun! Is this a bad idea for a first disco?

So far, I've read that P1884 has different subcodes, one which could be engine air intake temperature invalid
P0103: Mass air flow sensor fault
p0112: Intake-air temperature sensor fault
p1412: SAI Malfunction Bank 1LH
p1415: SAI Malfunction Bank 2RH

Thanks!

 

Skip it, the codes are not bad but they scream bad maintenance, and on a 22 year old truck you don't want one the owner skipped on maintenance. Unless it is literally zero dollars then it might be worth it.

Look for one with, no codes, no frame rust that runs with in temp specs.

 

RG makes good points. Not sure about 1773, but could be the truck is not that bad. For example, a couple codes might have been set if the connectors were left undone after cleaning the throttle plate.

A simple check is to look inside the oil fill hole. Black is no good, light brown is good (silver even better), chunky dark brown is maybe. Then how does the engine sound running? How does it drive? Do the codes return after clearing, then driving? Intake air sensor and MAF should be easy to fix. Rusty frames are difficult to repair.

 

Thanks both! I'm still chatting with the seller and haven't gone out to see the truck in person yet. I did just get the VIN to run a history though, seven owners! 140k miles so I wasn't expecting that many! One of them did seem to do a good job keeping up on routine maintenance, but no real service history on the others.

 

A question to always ask is, why are you selling? Some will sell a car if the repair bill is $$$ or theres a problem they don't want to deal with. If you buy it, then it becomes your problem. 7 owners is a lot, and could be an indicator of a hidden/intermittent problem that they didn't want to deal with. It could also be someone's project car, which can present plenty of potential problems down the road (ask me how I know).

What owner # did the most maintenance and when? Do you know what work was done? Big ticket items include head gaskets, oil changes, any work done/related to the cooling system, and plenty more (hopefully others can chime in!).

Seeing as your in Northern CA, I'm going to assume its a CA car so rust may not be an issue. Although are there any accidents on record?

 

Seller said they bought it with plans to fix it up, but personal issues keep them from it. I was hoping that the truck wouldn't be too much to take on (before I knew about all the codes and the number of owners), but maybe I'm biting off more than I can chew! They said head gaskets done in the past, but I'm not sure when.

Owner #4 was the one with the service history, between 75k miles and 113k miles.. oil/filter, engine serviced, and brakes serviced yearly. Cooling system serviced @76k, 86k, and 93k miles. Fuel system serviced twice ~80k miles.

Wish there were records from the other owners, but likely
#1 leased for 3 years,
#2 leased 2 years,
#3 had for less than a year
#4 owned the truck for a good 7 years
#5 might have been a dealer? Only had for a couple months and failed an emissions inspection once, before servicing and passing.
#6 owned for 5 years,
and #7 current has had it since 2023.

Seller is asking for 2500$ btw.

 

Seller just messaged me again and said they sent a typo - code is no longer a mystery! Added to the list is
p1173: P1173 Downstream fuel trim malfunction (bank 2) Front sensor aged - rear HO2S adaption too lean/too rich RH bank

 

I’d say $2500 would be cheap enough if the vehicle was in otherwise great condition (especially no frame rust) and the mileage isn’t too high, and you’re willing to do a lot of work on it yourself to catch up on the years of neglect. Otherwise walk away and find one in better condition.

 

I'm surprised at the ownership duration distribution. I was expecting 1-3 owners holding it for years, before 4-7 only having a year or less with it,


"Seller said they bought it with plans to fix it up, but personal issues keep them from it". This means there are more things that need to be fixed/looked at meaning you are buying a project car. There's nothing wrong with it, just know that there maybe other modifications or work done to it that shops haven't done. I bought a project car and have been dealing with issues/mods installed by the PO. Nothing too difficult just aftermarket parts to deal with. If you want a project car/fixer upper this could be a good contender.\

How handy are you and willing to work on this? Its a car that can easily be serviced with hand tools, lots of information/documentation on issues and how to fix them. It comes down to a matter of how time/money you are willing to put in on it.

 

I'm also surprised at the number of owners only having the truck for short time. It is rust free, but I think you're all right. I'm not particularly confident in my handiness (yet!), so something else in better condition will set me up at a better starting point. Thanks all!
