SOURCE: how to check transmission fluid on 2001 isuzu rodeo

There is no dipstick on your auto trans. Checking it is a real PITA The trans pan has 2 plugs in it. The one on the very bottom is the drain. The one in the corner, up higher in a recess is the check/fill plug. To check, the engine must be warm and running, tranny in P. Remove the plug and fluid should dribble out. If it doesn't it's low, fill until it dribbles out, while engine is running. Obviously the truck must be on a lift or up on jackstands.

SOURCE: Cruise control & check trammission light comes on my 2001 Rodeo

I had that problem too and the issue was a loose wire connecting the engine control modude to the crankshaft sensor switch. The engine control module does not sense where the crankshaft position is when the wire moves, and that causes things to go snaky, such as the transmission and cruise lights coming on. This issue took a good mechanic in Syracuse one and a half weeks to find. Total cost was $425.00,$395.00 for labour, and $.99 for the new wire. Good luck!

SOURCE: What does the diagnostic code

Hi, your vent valve has malfuntioned. The vent valve is near the tank, and has a hose to the tank and a solenoid to close it. Check the wiring/connector. If OK, try applying 12 volts directly to the solenoid. If it does not click when voltage is applied, replace the solenoid/valve.

P0446 Evaporative Emmission Control System Vent Control Circuit OBD-II Trouble Code Technical Description

Evaporative Emission Control System Vent Control Circuit Malfunction
What does that mean? Evap vent valve has only one purpose. It closes in order to seal the vent so the EVAP system can pressurize and ensure there are no leaks. Evap vent valve is usually supplied Batt. voltage with key on. The ECM's driver controls the ground, and when grounded, activates the valve (closing it). If the ECM detects a short to ground, and open,or a short to battery voltage on the control circuit, P0446 will set. Code also may refer to ECM detecting that EVAP system is unable to achieve or maintain vacuum during test.
Symptoms There will be no obvious symptoms to driver, other than MIL illumination.
Causes A code P0446 could mean one or more of the following has happened:

  • Faulty vent valve
  • Open, short or excessive resistance on Vent valve control circuit
  • Blockage of vent valve
  • Bad PCM
Possible Solutions With a P0446 OBD-II trouble code, here are some things to try:
  • Replace Vent valve
  • Repair open, short, or resistance problem in control circuit
  • Repair open, or short, or resistance problem in power circuit
  • Replace PCM

Where is the pcv valve located on a 2001 isuzu rodeo 2.2l 4 cyl

My guess, a USA car?
and is not 2.2L diesel guess 2.
its the 2.2L gas engine and is really GM/Holden.
we in USA do have 2.2L eng. gas, with DOHC belt drive cam.
Ok, my guess 3 is that you just heard someone say replace the PCV valve. but that person never saw your engine before, so was a generic , wish...
If you try to buy the part, you will fail.
(aftermarket of course)

OR did you fail to say engine leaks oil bad
and that PCV can cause this, it sure can.
its a system not a single valve. ever.

a word to wise some engines have no valve, Like old jeep 4.0 liter gas.

some have only an orifice, (that needs cleaned only or not... inspection work best)
so next i google for it, and get ZERO.
I then login to mitchells for you (so can you)
Know where there,(deep searches) shows PCV valve.

why is that?
answer is: IT is not there.
it uses some kind of special venting system.
in most cases its and orifice, fitting on the intake.

just posted this last week, my guess to you as anony. post2.

the above red line, may have pcv device here, orifice ,etc.
26105704-j1tz12pcffy4oogy4uqrcbj4-4-1.jpgsee this red arrow i think this is the vacuum port for PCV
clean that? is probably just and orifice fitting;
for sure it has:
1: a fresh air path to air cleaner.
2: and a vacuum suck side, with no valve.
on some engines its a Isuzu only section of pipe that if clogged, you clean it or replace the whole thing (very hard to source here)

here are all 2.2l , fix engines or buy parts
its best to know , what is there. (i dont)
2.2 L X22SE I4 (gasoline)
2.2 L Z22XE I4 (gasoline)
2.2 L X22DTH I4 (diesel)
"The 2.2 L engine was a derivative of the GM Family II engine introduced in 1995 built by Holden in Australia that saw usage first in Australian and European versions of Isuzu-derived trucks and SUVs, and was later used in the Isuzu Rodeo
found this post on a real isuzu form
no PCV valve as such on the engine, but there is a small restrictor on the inlet manifold gaskets - between ports 2 and 3.

2001 Isuzu Rodeo 4 cylinder Check Engine Light

Normally a shop would use a scanner to watch the operation of the EGR valve and sensor.
Code 401 means the sensor is telling the computer the flow is not enough. So the problem could be the sensor rather than the EGR valve. And yes one of the ports could be blocked too.

2000 isuzu rodeo check engine light flashes when at or around 2500 rpm and up. engine runs smooth and no codes come up ? light goes out when rpm is reduced.

are you checking code with a small simple scanner this will not always work, a larger more sophisticated unit may find code or runs codes at over 2500 rpms when light comes on
