Question about 2000 Isuzu Trooper

1 Answer

My 2000 Isuzu Trooper needs a catalytic converter.

The check engine light is on and the codes came up CAT/EGR. How many catalytic converters does the 2000 Isuzu Trooper have? I was told by a mechanic that it has 2 because it is the 3.5 V6 DOHC engine. Is this true? Also, if the catalytic converter(s) is bad does that mean that the EGR valve is bad also?

Yes they have 2 cataletic convertors, one each bank
there is EGR codes, but only front O2 sensor codes and fuel trim codes no CAT codes
what were the scanner codes or flash codes i can work with both for helpful info
you can read codes by bridging pins 5 & 6 with ignition in on position engine not running

There are no leads under left kick panel, I have 16 pin with leads going into 1,2,4,5,9,12,13 & 16. So, which ones do I bridge to get codes?

Check engine light Po420... What is the most likely cause for an EGR flow insufficient problem


The most probable cause would be blocked system. However code p0420 refers to catalytic converter system bank 1--efficiency below threshold===causes--catalytic converter faulty---wiring ---HOS2. It is more likely that the oxygen sensor needs attention and the cat converter needs replacing

I have a 96 Honda Civic HX. When I am at idle the car starts to shake and the rpms fall almost to zero. I took the car to a mechanic and was told that I need a new Catalytic Converter and the EGR ports...


Yes and No. The EGR can cause the car to idle rough and or stall. I am assumeing the check engine light was on and set code for EGR and Catalytic Converter. If the engine isn't running right it is possible the cat won't work right due to improper air fuel ratio that the EGR is causing. To do repair proper the EGR should be fixed then clear codes and see if the code for Catalytic Converter. There are other reasons that would your car to idle rough or stall I am just assuming that this mechanic got codes or tested the EGR right.

Your SUV is really giving you a hard time, lol. Sorry but I've had those days too.
I would try to check if you have blocked EGR passages. If ok check for restricted MAP sensor vacuum hose/passage or restricted exhaust. I know you replaced the CAT but if the muffler is blocked then there would still be a restriction. Also check the wiring and connection to the MAP sensor.

New catalytic converter gets red hot


clogged , check the rest of your exhaust after cat to see if it gets hot

you can buy a no contact thermometer for less than $55.00

but the shop that installed the cat should have that

good luck

Check engine light due to Catalytic converter


Without knowing the specific code, I will assume it relates to an inefficient catalytic converter. At this mileage it could very well mean that the catalytic converter is failing to do it's job and needs to be replaced. The computer sets this code when it sees a signal from the rear O2 sensor start to change in time with the front O2 sensor. It should not. If the cat is working, The rear O2 sensor should have a stable output as the cat is supposed to be removing all the oxygen from the exhaust. Sometimes this code will set if the spark plugs or the engine's state of tune has deteriorated and is producing more emission than the cat can handle, the rear O2 sees the overflow and assumes the cat is bad.
At your present mileage, I would strongly suggest changing the spark plugs if they have not been done in the last 20,000 mi. Have the light reset and drive it to see if the code returns. If it does, replace the catalytic converter. I suspect that you do need a cat, but I view the spark plugs as maintenance, and I wouldn't want to put a brand new cat in without the assurance that my old plugs were not going to damage the new one.
Hope this helps,
Dave

Determine which O2 sensor to replace.


There are many reasons for a PO171 code, these need to be checked before replacing O2's:

  • Vehicle driven low on fuel or until it ran out of fuel
  • One or more injectors restricted or pressure regulator has failed
  • Fuel delivery system supplying too much or too little fuel during cruise or idle periods (e.g., faulty fuel pump, or dirty fuel filter)
  • Air leaks after the MAF sensor, or air leaks in the PCV system
  • Air leaks at the EGR gasket, or at the EGR valve diaphragm
  • Exhaust leaks before or near where the front HO2S is mounted
  • HO2S is contaminated, deteriorated or it has failed
  • Fuel control sensor is out of calibration (i.e., ECT, IAT or MAP)
  • Base engine "mechanical" fault affecting one or more cylinders.

    Oxygen Sensor on '99 Isuzu Trooper


    The O2 sensor is on the engine side (up stream) before the catalytic converter in the exhaust pipe, it is barrel shaped about the size of a jumbo magic marker.
