Question about 2000 Isuzu Rodeo

2 Answers

2000 Isuzu Rodeo, 3.2, 112,000 miles, Service Engine Soon light is on, won't pass inspection till I get it cleared off. Hooked up a scan tool the only code is P1340 and it scan tool says it's a Manufacturer Specific Powertrain Trouble Code. Not listed in Haynes manual. Cleared the code with the scan tool and it came back within the same day about an hour later. Anyone have a reference to what code P1340 is? Something I can look into myself? What repairs need to happen? Estimated Costs? Johnny --------------------------------------------------------------------------------

Reduced power light comes on no power can't get over 30 miles an hour. RPMs not good at all. 2004 Isuzu Rodeo


A serious fault has occurred in the engine or transmission and the powertrain control module has reduced power to prevent any further damage to the drivetrain, I know that the check engine light is on as well. What you must do now is have the fault codes read with a OBD2 system code reader, once you have these fault codes you perform the needed diagnostics and repair the problem, There are no quick fixes.

Reduced power light is on in my 2001 Izusu Rodeo Sport


the Reduce light, is not transmission , light correct?

what country are you in., ( asked 10000 times zero answers .well 3)
what engine,? we cant guess engines, here, and it seems to be just that, the engine issues.??? felt is real;. sure..

is the tranny stick or auto...... autos can slip and go to limp home mode just like engines do. so what transmission?

if in USA all scan tool made will scan an ISUZU. 1996+
so then you see DTC errors. and why its in limphome mode.
"your reduced power deal"
there is no other way,,,, besides, 1000 pages i type on how to test EFI with not scan tools.....I can do it. but refuse. to type that here..
as one famous poster said.
you want 50 years experience on 1 fixya page. :LOL

i wont say that, I say.
1: check all fuses.
2: make sure battery, voltage is 13.3 to 15v running, if not you have charge system failures, fix that first because EFI will not run on dead batteries, ever. (discharged for any reasons)
3:Scan it. do so and tell the DTC errors, im sure you have them.
4: or did you skip the 60,000 mile major tuneup, or never did one this decade,,,, wow, that be why , huh?

Engine light will not go off in Isuzu Rodeo 2010, yet nothing shows up on diagnostics. How can I get it off long enough to pass inspection for my state will not pass vehicle with engine light on?


Test this out once, disconnect the battery completely (both pos. and neg) for around 5 - 10 mins, put it back on and test drive if it comes back on it should have a code then if it does not it was probably a phantom code
let me know how it goes

I keep getting a service engine soon light on and NO CODE on OBD


Have someone check it with a different scan tool it possible.Not all scan tools will work.If the light is coming on and you notice the vehicle is not running the same as before,there is a code in there and you have to get that code to diagnose the problem.

My 2000 Isuzu Rodeo also shows chech engine sometimes.


Most onboard computers store error codes so even if the light is not on a scan should show what error is causing the light.
Get it scanned and take it from there , It's the best option and it will give you piece of mind.
Some car part stores Scan for free or a small very charge.
Hope this helps

Engine knocks 3.2 isuzu rodeo 2000 ? help


You don't say how many miles or give a service history, but, that said I would check the timing belt and tensioner. When tensioner goes bad is often is reported as a loud knock or tick. Usually most evident at low RPMs. Another low cost try is to use a can of seafoam in the oil now, run it a few miles, then change it for a high detergent, low viscousity oil and drive it a while to see if the lifters clean up. engine tick is very common, generally due to lifters oil passages getting sludged up a little for 2nd gen 3.2l's
