Question about Toyota Highlander

I just bought a 2003 Toyota Highlander. After 2 days the check engine light comes on. The code ran a bad catalytic converter. I paid to have it fixed. 3 days later... same thing happened. What's the problem?

If you had the converter replaced, the check engine light could be caused by a faulty O2 sensor. Just out of curiosity, did you keep your old converter? The reason I ask is, you can recycle the old converter for quite a bit of money. Some converters bring more money than what the new one cost. If you didn't keep it, the muffler shop will recycle it, and get paid double for fixing your car.If you have a receipt for the work, and it hasn;t been long since you had it worked on, take the receipt to the shop and ask for your old converter back. If they have already disposed of it, ask for one like it. It's money out of your pocket. And the muffler shop should have asked if you wanted to keep it.

Why Did the Vsc and check engine light come on in 2005 toyota highlander?


The converters generally fail only after the truck has been running rich. I would not replace them until certain the engine is running properly. There is no harm to the car to drive with these converters. Was there any history of rich operation codes?

Catalytic Converter Replacement Repair Cost


code p0420 refers to catalytic converter system bank 1 --efficiency below threshold ===causes -- catalytic converter ---wiring---HO2S 2 sensor
The cheapest part to replace is the HO22S sensor so I would do that first. Bump the cat converter soundly with the heal of your hand and if it rattles it needs replacing as it will be cracked internally. Dismiss any tinny rattle as that will be the heat shield loose
The time taken to replace both in an accredited shop will be less than 1 hour so it may pay to shop around and compare prices on the converter and labour costs.

2003 Highlander CE light, scan codes P0420 and P0430. DO the appearance of both 0420 and 0430 indicate that problem is most likely the Catalytic converter? Or might it still be a problem with either or...


code p0420-430 refers to both cat converters (bank 1 and bank 2)--efficiency below threshold== cause cat converter- wiring --- Ho2s. As cat converters are subject to cracking and failing and thereby not doing the job I would suggest having them checked and replaced if necessary. A local exhaust shop should be able to do the job . If they are cracked/broken there will be a rattling sound when the exterior is hit

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.

The vsc light and the trac off light and check engine light all came on at the same time code p0420 comes up on my 2005 highlander what does this mean?


A p0420 sets after Engine and catalyst are warmed up, vehicle driven within set vehicle engine speed range and waveforms of heated O2 sensors bank 1 sensor 1 and bank 1 sensor 2 have the same amplitude.
Catalytic convertor and O2 sensors need to be tested

Engine code 430 for 2001 toyota highlander


Possible Causes:
Oxygen (O2) sensor not working correctly
Damaged or leaking exhuast (pipe, manifold, catalytic converter)
Damaged catalytic converter

Diagnostic Help:
To diagnose a P0430 trouble code we begin by checking for exhaust leaks under the vehicle. Then use an oscilloscope to check the waveforms of both upstream and downstream O2 sensors. The rear reading should vary, the front should be steady. Replace as necessary. Check the rear Heated O2 Sensor. Check the catalytic converter, replace if necessary. If necessary, check for wiring and component. hopes this helps thanks

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.
