Bad catalytic converter?

My 2003 nissan pathfinder recently failed the e-check test, check engine light diagnostic showed left side front catalytic convertor was below threshold allowable. I was told cost for after market part was around $750.00 plus labor puts it around $1100.00 to fix. Is there a limit to the cost involved to conform the vehicle to the echeck standard?

Log onto www.partstrain.com. I believe they have Catalytic converters for your pathfinder for under $200.00, there OEM direct fit which means no cutting other then removing the old bolts.
If it is the Catalytic converter you can always buy it from on line and have a muffler shop install it like speedy or midas. Make sure you ask for stainless bolts and nuts.
Before you go through all the trouble, re check the DTC codes. Most of the time it's the O2 sensors that go bad and i question the garage charging you so much for the replacement of a catalytic converter.
Good luck and keep me posted.

Below threshold huh, looks like maybe your cat is clogging up and not able to let through enough exhaust. Well, this is what I would do. Go buy a CAT converter, aftermarket or not, get a grinder or a pipe cutting tool, cut your original CAT out, then weld or have someone weld or fix the new CAT in place with exhaust sleeves/adapters. Whole process should cost no more that 400 dollars if you have a shop weld. If not, should be around 300 - 320. Good luck.

    I agree with Molson, they are overcharging you for whatever needs to be done. Way too much for a cat replacement. Because look at it money wise, hour labor - 70 dollars, new cat "THEY GET DISCOUNTS" so a new cat to them, should be cheaper than you buying it. So either way, they will spend around 150 for cat...+140 for labor, = 290. So why charge so much?

What is code p1055 2003 Toyota Highlander base model


The code 1055 is brand specific, and for Toyota it means there is a problem with the heater circuit for the O2 sensor bank 2 sensor 1. That is the sensor in front of the catalytic converter or split and on the side with cylinder number 2 which may be the passenger side.
The sensor could have failed, or it could be a problem with the power source for the heater inside the sensor.

i would definately replace the coil. pretty certain that will solve your problem. do not drive with misfire or that can cause fruther damage such as catalyst failing, which is prety expensive.

Need to replace bank 2 sensor 2 on 2003 toyota highlander , where is it located


Bank 2, sensor 2 is a heated O2 sensor located below (after) the catalytic converter on the passenger-side. When this sensor gets clogged and/or goes bad from rust and heat fatigue, the voltage drops low enough to cause the electronic control module to register error code P0161, which then causes the check engine light to come on.

To replace Bank 2, sensor 2, remove the debri shield from just behind the front bumper, underneath the vehicle. There will be 10 bolts holding it on (10mm, I believe). After removing it, look toward the center of the newly exposed area and you will see 2 finger-like objects projecting out from the engine with wires coming out of each. The one on the left (passenger-side) is bank 2, sensor 2. The one on the right (driver-side) is bank 1, sensor 2.

I got my direct-fit sensor online for $55 from Remart Auto Parts. I know it is tempting to get the universal-fit type and save the cash. But after doing that once, I wouldn't care to do it again.

I found a YouTube video showing pictures of where the two lower (after catalytic converter) sensors are located. While the video only points out the driver-side sensor (bank 1, sensor 2), it's easy to spot the other one being only inches away.

Bank 1 is the converter on the side that engine cylinder one is on. Yes that is true about the converter, the computer is programmed for a certain value, an aftermarket cat will not meet that value and the check engine lite will be triggered.
