You are welcome. I went back and revisited the Service/Workshop manual for the 02 Axiom and cannot really find a connection between the error codes you are getting and the throttle body. However, that does not mean that there isn't one... in fact the PCM that he is recommending you replace, serves the throttle body.
The throttle body is basically a carburetor-like device with an electronic DC Servo motor mounted on the side, and some sensors attached nearby it. So it is key to your vehicle running right.
I do wonder, though, why he wouldn't opt to CLEAN the throttle body and REPLACE the PCM, rather than do a REPLACE/REPLACE. Of course, I am not there, and don't have a Tech2 scanner to check your vehicle, which your mechanic may have done. There are some troubleshooting steps detailed in the manual that he would have had to do to come to the conclusion that the throttle body needed to be replaced. I just hope it's not a guess on his part, as the T.B. is probably an expensive part.
Then again, "in for a pound, in for a penny" might apply, since if he replaced the PCM and it still ran like crap, he would have to replace the T/B next. I just wonder if it wouldn't be possible to clean the T/B rather than replace it.
A worthwhile and legitimate question to ask your mechanic is this: "what in your opinion indicates that the throttle body needs to be replaced, rather than just cleaned?"..., and related to that, "can we just clean the T/B and replace the PCM and see how it runs?" It would seem to me that you can always go back and replace the T/B if that does not work. Cleaning the T/B should be relatively inexpensive compared to replacing it.
I do not mean to cast doubt on what your mechanic suggested, as he could be in the right on this, but it is worth checking out. Given the cost, you could always check with your local Honda dealer service department, as they should have the tools to work on your Isuzu and can render an opinion on it.
Finally, if you want, I can give you my copy of the 02 Service Manual. I don't need it anymore and it is in PDF format. Send me an email to "inboxbancca.org", replacing the with the "" symbol, and I will give it to you and you can pour over it for yourself. It's very helpful and detailed manual - the shop manual that the techs use themselves - and is searchable. Might help you sort this out for yourself.

Is it possible to go back to the shop and tell them they have your key. I had a similar issue with Tires Plus where they kept my wheel locks on another car. Ended up going through their corporate offices for them to reimburse me.

We have the same issue and they said we need to replace the wire harness. We also replaced sensor, fuel injection system, computer, calic converts, and more. We are at our end. Did you ever get yours running again and how?

There are just a few manufacturers of the wheel locks. I think the main company is McGuard out of NY. Most OEMS use them I think. Most dealerships and tire shops have a master set of about 10 of these keys in a kit, and they use them to take off the tires on cars instead of hunting for the owners key. At our store, -when someone is missing the key, we match up one of our keys with the locks on the vehicle. that key has a number on it and the dealer parts department orders a new lock key from Mcguard. less than 10 bucks if i recall. You might call mcguard and see if you were to trace one of you exiting locks could they match it up with the master key. If you still have the box or label from the original kit there is also a number for the key kit. I have an 03 axiom bought new and i do not have the locks. they were a dealer installed option. Mine just turned 76K. I replaces the f and r disc brakes rotors and a caliper a year ago- had about 65K on it. Only other thing I replaced was an o2 sensor, I bought for 30 bucks new from rock auto. I did have the intakes gaskets replaced in the spring. Also have had a new battery and tires. I think my axiom is so trouble free compared to Toyotas I have seen, they have their issues. My 2000 rodeo with 100k had never had an o2 sensor replaced. he intake gaskets this past year, and a front abs cable. Brakes and tires. Don't forget changing your pcv valve every 25k miles. very important to keep the vehicle from using oil. I use less than 1 quart of oil in 5k miles. regards.
#2533 of 2537 Replace Axiom transmission?
Mar 16, 2013 (9:48 am)
I have a 2002 Axiom that is having transmission problems and may need a new one. I bought it new and really love the car! BUT does it make *any* sense to install a rebuilt transmission in an Ax w 127,000 mi on it? The dealer replaced the trans under warranty at ~50k and is quoting $6k for a rebuilt.
Any advice would be appreciated!

Hi are you sure it is the transmission and not something else? A sensor or something. Seems premature but trans can go on anything. We replace some on Toyotas at 60k or less. I have an 03 axiom bought new with about 88k on it. It has been a great car, only thing I have done to it is to put tires, battery, brakes and last year new intake manifold gaskets, and prev an O2 sensor. that was not a big deal. 6k is too much for the dealer tranny but if you like the car and its been well taken care of in other areas, and the brakes and tires are good, and you have had frequent LOF's and engine maintenance then it can be worth it. You can not buy any good used cars for under 5k these days, take a look. The one thing you need to do if you have not, is to change the timing belt and water pump at 100k if you have not already. I need to do that on my 2000 rodeo, bought new, 109k and it needs a new transmission as well, as it had a small leak in the modulator valve seal, it was replaced, and was running fine for a few weeks until the seal blew on the highway due to the trans shop not putting in the retaining ring correctly. It now won't shift into 4th overdrive, but runs great all around town in 1-2-3. AT 60MPH is is doing 2900 rpm's which is high ad won't go into 4th. some times It will and then you hear it shirt up and all is well until you drive at slow speeds and the shifting is very harsh, Shut the engine off and the thing resets, light goes off and it runs fine in 1-2-3 but won't shift up to 4th so the rpms can go down to about 2200. It is rare that it happens. Anyway, 2 local trans shops have given me a price of 1800 or 2400 to rebuild it. I have also checked with Rock Auto.com and they have rebuilt transmissions from a good company for about 1800 dollars with a 3 yr 75k warranty if installed by a trans shop. A few places said it would about 500 to install is so I am considering that when the time comes. This is a GM transm. 4L30E if I recall. Both my cars are like new in and out. The rodeo has had only 1 item go so far, a front ABS brake sensor that I had a dealer replace a few years ago. Also minor thing like a new door light switch and a door check stop. Both I put i my self at about 25 bucks each. Other than a few warranty items when the car was new, in 13 years thats it. I can not complain at all. But I know I should be putting in the new timing belt. Oh and its important to change the PCV at least every 50k. the book does not mention it but it will prevent excessive oil consumption if clogged. It is pretty easy to change. As you look at the engine it is on the right bank on top of the valve cover. When you remove the plastic cover be care taking it off, it pulls straight up but there are 4 rubber grommets under the plastic cover that hold it to the 4 pins around the manifold so when you careful remove the cover be sure the grommets don't fall out into a place where you can not retrieve them. I tape mine to the cover so that when I put the cover on they stay in place till I force the cover down in place. Also be aware that your PCV valve should be metal and has a hose coming off if it, and screws into the valve cover. It was about 10 bucks at the dealer. Be aware of aftermarket ones as the listings are often wrong and may list the plastic ones that just press into the valve cover and were used on pre 01 model rodeos and troopers. Early vehicles would have a tendency to use oil if the pcv valves were clogged and not replaces. So far I barely use a quart of oil in either of my vehicles in about 3k miles. well hope some of this info helps as you did not mention what the issue was with he tranny. Good luck and let us know what you find or if you have any other questions. ken/boston

Hi, sorry to hear about your issues with your Ax. I have a 02 and had the transmission replaced at 60K by the dealer (they had a lot of issues with trannys then). I also had my transmission rebuilt 2 years ago at 165K, it was done by a small tranny shop and cost me $1600 in all. I thought it was a bit much till I saw what the dealers were charging. The shop also gave me a 1 year warranty just as the dealer would. I'd suggest shopping around for good tranny shop.

Thank you both for your helpful responses! The problem with the tranny was that it started slipping at odd times (when hot?) - the engine would rev, but the car would move slowly or not at all. However, if you shut down and sat for 5-10 mins, the car would run fine then for awhile. We took your advice and found a well respected local trans repair shop for diagnostics.
Meanwhile, we looked at new cars -- the Santa Fe and Outback were contenders, but neither had the power or interior size of the Ax (mileage was a different story, along w gee-whiz electronics, but as I said, I love my Ax!). Anyway, a rebuild is under way, and we're looking forward to more years w the Isuzu.

Glad to be of assistance, good look with your AX, I know I love mine. I also thought about putting it out to pasture as Isuzu went out of biz, but I'd rather drop 3 grand in it and have good running car that another payment of 32 grand over 5 years.
What I do is put $300 in a savings account monthly as if I'm making a car payment, in about 5 years I'll have a good amount for a down payment on my next ride if the Ax holds up.
