Help! Has anyone had a dealer repair shop tell you the Main Engine Wire Harness needs to be replaced? My problems started with a transmission fluid leak, the dealer replaced the accumulator pison ocver, which Ilater learned is defective in most 2000+ Isuzu Rodeos. Then, the ck trans light kept coming on, and it felt like the trans was slipping. Back to the dealer, they told me my trans was shot, buy a new car. I learned it was under the $120,000 warranty, back to dealer, okay, it's covered. Then a phone call from the dealer,it's not your trans is the Main Engine Wire Harness. Any suggestions?
Thanks...

Sounds like you are driving my Rodeo!!!! The only difference is that I received a call this morning saying it wasn't the trans. The piston cover and gasket were replaced a couple of weeks ago. The trans is still slipping and their is a lot of engine strain/whine. Now they say it's a coil. I'm 8K miles from the end of the warranty and don't want this to go unnoticed by the dealer. As a side note, when the dealer replaced the cover and gasket after the fluid leaked out, they charged me $200 for new fluid saying it wasn't part of the warranty! I had just had the trans flushed the previous month. Sounds like faulty work to me.

#12 of 137 2003 Isuzu Rodeo Check Engine Light - Fuel Cap by t2frisco

Jul 23, 2006 (5:56 pm)

Three clicks on the fuel cap are NOT enough!
 
Upon refueling my gas tank on my 2003 Isuzu Rodeo and following the 3-clicks rule, the Check Engine Light (CEL) came on! When I stopped to make sure the fuel cap is tighten, the warning message on the fuel cap "Check Engine Light may come on" stands out like "I told you so". When I got home I got on Google and read most of the posted problems related to the CEL.
 
Then I disconnected the battery cables to reset the computer and waited for 5 minutes. After putting the cables back, the CEL goes away.
 
The 3-click rules may be 4 or 5 or bunch click to make sure that the sensor sees the cap being closed!
 
The CEL is a latch desgin. Once the fault is triggered it won't goes away until it is instructed to clear. One way to clear the latch is to disconnect the battery cables for about 5 minutes. There are two fuses, namely ECM Main and ECM Backup, in the fuse box under the hood on the passenger side. Maybe taking those two fuses out also resets the computer but I haven't tried it yet!
 
I don't know how the fuel cap sensor works though. I don't see any electrical connection out of the fuel cap!

Having a shifting problem. We live on a rough country road. Rodeo had problem when we purchased it three years ago. Mechanic at that time messed with a sensor,[ would not tell me where it was], problem then cured. Can not locate this sensor. Truck is mrs. so can't give better clue, has been serviced, could not get to spark plugs { hidden?}. Can you give me clue where to start? Waynes manual doesstate or show where sensor is or how to get at plugs. thank-you for any help you may have. Hardridincwby

#15 of 137 98 RODEO- TRANS LIGHT BLINKING- CHECK ENGINE LIGHT ON AND ABS LIGHT ON by kstjmy2

The transmission light just started blinking and my check engine light has been on forever and the ABS light is always on. We have put it on a scanner and it says that the cad.converter or O2 sensor but nothing on the ABS light- Just changed the brakes on it and I have no idea why the trans light is now blinking? Anybody have any ideas.

This sounds odd but, check alternator. If a triode on the charging side is even slightly weak thing get weird. If thats not it, check sensor on rear axle. Ours wiggled loose, hard to diagnose.
 Good luck

#17 of 137 2001 rodeo lse by bucsngoofy

hi, just got a 2001 rodeo lse, love it, however, the cruise control keeps engaging on it's own, and if i don't catch it right away, it totally makes my car die!! the cruise set light and check transmission light comes on, if i catch it i can disengage it, but otherwise my truck just quits on me! have taken it into a friend who's a mechanic, nothing comes up on the diagnostic check, we wanted to just take the cruise out, but i guess in the rodeo there are two computer systems, instead of just one, and he doesn't know which one it would be in!! he doesn't charge us, so that's why we haven't gone to a dealer yet, does anyone know anything about this?

I bought a new aftermarket locking gas cap and every since then I've been getting the CEL to come on sporadically. The CEL does turn off after the computer cycles enough times to clear. Going to try the battery cables. I only get the CEL every so often now, because I realized you have to keep on-a-clickin' the cap.
