Engine swap

Hi,

Is there a reason you want to change the computer? I would suggest keeping the wiring/ computers and modules original and swap the sensors and such on the engine itself.

If you do that along with the tone ring, you shouldn't have wiring issues. Anytime you try changing the wiring from different years, colors, routing, and so on becomes a nightmare.

I would be happy to provide the wiring schematics for both years (powertrain management schematics) if you want.

Let me know.

Hi,

If the original one doesn't have a place for the EGR and the replacement does, it's not a big deal. You can either purchase an EGR delete plate or leave the EGR installed. It won't open.

If it was the other way, then there would be federal emissions violations. However, your original engine didn't have it, so it doesn't need to have it. (If that makes sense).

Let me know if I got that the correct way. LOL

Take care,
Joe

Hi,

Let me know if I can help. If you need any wiring schematics, I can get them for you. Also, I thought your vehicle didn't have an EGR and the new engine does. If that is the case, it shouldn't cause the light to turn on simply because there is nothing to attach.

I may have it backwards. The original may have had one.

Let me know if there is anything I can do to help.

Hi,

If none of them are working, something is disconnected, we have a ground issue (unlikely), or a blown fuse.

Hi,

That is Chrysler's scan tool with the software for their vehicles. By any chance can you get your hands on one? Also, you should be able to do it with a different tool if you have one that can actuate things and get into the different modules.

Let me know.

Hi guys. I have a DRB3 if you're near north central WI. I also use a Snapon Solus Edge.

With an extra plug-in card, the DRB3 will do emissions-related stuff on every brand of vehicle sold in the U.S. Starting with '96 models. For that reason a lot of independent shops bought them. They're obsolete now, so you might find a shop owner happy to sell theirs so they can invest in something newer. You can find them on eBay too.

Snapon is very proud of their annual updates for their scanners, and they charge accordingly for them, as in around $1,000.00 per year, and you can't skip any years. Look for one of these on eBay that is outdated. For example, if you find one that has been updated through the 2014 model year, a shop that wants to use it on customers cars would have to buy the 2015 update, at $1,000.00, before they could buy the 2016 update, then the 2017 update, etc. Four or five years of updates cost more than a new model with all the latest updates, so it doesn't pay. That makes them lose their value very quickly, and you can pick one up very cheaply. All you need is to find one updated enough to cover all of your vehicles.

Hi,

Some Harbor Freight tools are worth their weight in gold, and others, not so much. LOL Just make sure if you get one, to read what it is able to do and make sure it covers your vehicle.

Hi,

Try providing a ground and see if it helps.

The first three pics below are all the ground locations for the 02. The last three are for a 2005. See if anything there helps.
