Is there a "computer flash update" for my 2001 isuzu rodeo ls 3.2l (v-6)

I am at my witts end with finding any solutions for getting my car smogged. That check engine light won't seem to stay off. Computer codes that keep popping up are: P1120, & P0401. Money is somewhat been an issue, but I just don't remember ever buying a second house, if u know what I mean! Please, car is our travel means. Single dad, 3 young kids, mom still nowhere to be located(her choice). Aaron

Code p1120 refers tothrottle position sensor1--circuit malfunction---causes ---wiring open cuircuit--/short circuit to ground/short circuit to positive---throttlecontrol unit---ECM
code p0401 refers to exhaust gas recirculation(EGR) valve system---insufficient flow detected. ---causes hose leak/blockage--basic setting not carried out (if applicable)---wiring---EGR valve---EGR solenoid----ECM. I would replace the EGR valve for starters Get unit from the wreckers. You may have to have the CPu reset with a code reader tool

Is 2001 Isuzu Rodeo LS 4wd owner's manual same as 2000 and/or 2002?

Yes, they are basically the same, except for paint color combination and a few other changes in interior.
Other than that, the drive train and engine are the same.

I'll have to see if I can find a PDF online.

I have code P0401 on a 2001 I SU RODEO V6

You've probably fixed this by now. I had the same problem and it wouldn't pass the smog check. I thought I'd have to replace the EGR valve but now know that would have not solved the problem.
The solution was to remove the EGR valve, plug the rear hole and use some carb cleaner down the other hole. I'd get two cans. I sprayed a bunch of liquid in the hole but it just filled up. Had my wife come out and rev the engine for a bit. Finally, the liquid got sucked into the port and I sprayed an entire can in while she kept the engine RPM up. Bolted the EGR valve back on, took it to the Smog check place and it passed with flying colors.

Failed Smog Test - 4 codes for 2001 Isuzu Rodeo

Tune it up and replace the 02 sensor that keeps setting the codes bank 2 sensor 1. Have your oil and filter changed right before you go for a retest to. That will clear up 3 codes P0300, 0155 and 0154. You might have to replace the fuel sending unit to get rid of P0463 but if the gauge works OK I'd leave it alone.
