Celica :: 2000 Toyota GT Sputtering / Jerking - Code P0420
Dec 1, 2013
I have a problem that has being going on with my 2000 toyota celica gt has been sputtering/jerking when going at a constant speed of about 60 mph. The problem is interment. I have changed everything from cam sensor when it came up on the scanner. Also changed the fuel filter and fuel pump. I changed the spark plugs. No luck the problem went away for about 2 weeks when I changed the fuel pump and filter but it came back. I got it scanned and the only code that comes up is P0420 which is a catalytic converter code. I have no clue where to go from here.

I was just driving and suddenly i had my CEL pop on. I went to pepboys to have them read the code for me and it Came up P 0420. I have been looking up the code and got a few emissions issues but not sure what one to do first. Any link with Main issues for CEL Codes? Or know what it could be?

I have an Hyundai Accent Petrol 1.6L ABS.
While driving the other day suddenly the car started sputtering or jerking while on low rpm and after changing gears
the exhaust is also making sputtering sounds when on idle.
when I press the accelerator the sputters/jerks and then picks up rpm. the performance of the car does not seem to be affected but petrol mileage has fallen.
when I accelerate slowly then the sputtering/jerking is reduced and sometimes not present much. There is also a deep and heavy sound of the engine running heard inside the car (which has been present before the timing belt change)
I took the car to the workshop and attached the OBD.
the codes P0340 P0112 were present. we now erased the codes and the mechanic checked the sensor wire plugs for the cam sensor and air sensor saying it looks fine. on attaching the OBD again the codes were not present. However the sputtering/jerking continues. (the fuel pump and filter were also checked to be ok)
My Timing belt has been changed approximately a month back. My car does not run much (Approx 40kms a day)
My questions are
1. can a bad timing of the timing belt have anything to do with this and thus giving these codes?
2. Can there be something wrong with the exhaust due to which this problem is taking place?
3. what could be possibly wrong with the car?
4. Can this result in any damage to the engine?

My Toyota Tacoma is reporting (via an affordable OBD-II scanner) the same P0420 code: First as a regular code, then as a pending code. What could that mean?

I have recently had about $1620 worth of work done on my 2000 4Runner because the check engine light came on and the code was P0420.. My invoice says they replaced the exhaust pipe assembly. Now 2 weeks later the light is back on with the same code...are the 02 sensors part of the "exhaust pipe assembly" or are they now going to tell me I need a bunch (2-4) 02 sensors replaced.

2002 4Runner 4x4, 180K miles. I bought this car about a year ago and don't know anything about its history before that but it seems to be in good shape.
About every month or two I take a trip that includes driving a few miles on a dirt road. It is a graded road in pretty decent shape. What has happened about 6 times during the year is that the CEL comes on while I am driving on the dirt road. The car continues to run well. When I get home and hook up my code reader the code is always P0420 Catalyst efficiency below threshold.
To save everyone the trouble of looking that up, this code indicates that either the upstream or downstream A/F Ratio sensor is bad. If both sensors test good then it is probably a bad cat.
What is different here is that after I clear the code, the CEL stays off as long as I stay on paved roads. So to summarize, I don't get the code every time I drive on a dirt road but every time the CEL has come on it is while I was on a dirt road.
So it seems that something about driving on a dirt road causes the CEL. Two obvious things you get on a dirt road are dust and vibration. What could be causing this? I did a visual inspection of the whole exhaust but did not see anything obvious such as cracks or leaks.
And of course I could live with this if I have to since it comes up under such limited circumstances. I just like to keep my cars running properly.

Symptoms:
-Car "Surges" at any speed. Loss of power is significant.
-Check engine light is on , DTC code = P0420
Tried:
-Fuel injector cleaner
-Spark plugs replaced around 40k miles ago
-Checked for leaking valve cover gasket (oil in plug wells) None
Can a clogged fuel filter cause this? At idle the car is fine, the symptoms seem to only occur when car is under load (In drive). My son drove this car an it always seemed empty meaning he never put much gas in it.

I have a 2003 Toyota Corolla, mileage app. 106,000. Check engine light first came on when driving to destination 40+ miles away (most of my driving is shorter, around-town trips). My mechanic said code is P0420 and so they reset it and said if it comes on again that I need a new cat converter. It did not come on until about 6 weeks later when I was on a longer trip again (had driven about 40-50 miles). Can you tell me if the P0420 code absolutely means that a new cat. conv. is needed or if it could possibly be a sensor or something else hopefully less costly than a new cc?

I have Toyota Camry 2005 LE, 180.000 miles ( first owner )
Few months back I noticed that my Camry is sputtering on low RPM below 2000 ( but never when engine is cold )
Car is driving perfect on the highway but in the city sputtering get very annoying when on low RPM and high gear.
My remedy for that is to press overdrive off button after this sputtering always goes away.
My transmission fluid level when HOT is 1 inch above HOT mark
And when in cold next ( morning ) label is still above HOT mark
Fluid level never goes down to COLD mark
What are the cause of the tran fluid be on same level and can sputtering be the symptom of it?

My 96 toyota celica check engine light is on and I get the code P0340. Also I can't seem to get my reverse light to work what could be the problem.

The check engine light on my sons 03 celica is on. Went to autozone and they got the codes for me. They are P0420, P0442, P0446, P0456. I realize that I should probably have an OBD11 reader. What steps do I take to fix this?

I was driving my 2000 celica gt and it started making an awful sound. It was clunking and started slipping. The rpm's held constant but the car was going slower. I had it towed home. I have driven it a few times and the noise is still present once the car was going down the road in third gear and the front wheels locked up and the car screeched to a halt. it can be put into gear and driven at slow speeds. I assume that the transmission has failed. If it is in fact the transmission there is a gt-s with a 6 speed at the local junk yard. From what i read the swap is direct bolt in. Is that true and does the shifter need to be changed?

Where the CCV and its VSV are located on my 2000 toyota Celica? Is the CCV also called the Evap vent valve?

My girlfriend has a 2000 Toyota Celica, and one of her tail light covers broke a while back. I'm pretty sure I can replace it myself, but with the age of the part, is there any source for a used replacement? At the moment, I can't remember which one it is, but I could replace them both if I could find a matched pair.

I have had a problem where truck would start jerking and sputtering in a certain town at low speeds. Today it happened in a new place. Barely got it to start back up. Was running rough after the puff of black smoke. Its stranded at a gas station. Recently replaced my sending unit. Was running good. Clean gas tank. Fuel lines tight. Where should I begin? I have an ICP sensor in the glove box. Truck wouldn't start.

I have a 97 4runner Automatic that as your driving it hesitates between shifting its gears. Most prominently happens around 80km/hr shifting between gears.
Its a sort of soft sputtering/jerking motion momentarily. It does shift into the gear and does drive fine once its in the gear. My check engine light is on as well now....

Toyota celica 2000 GT automatic, has a problem on cold start, especially when the temperature is below 32 degree Fahrenheit. The engine starts and runs roughly, but most electrical devices do not work, the dashboard and car windows are power off and I can't change the gear so it can not move. Only after warming up for about 10 minutes then the dashboard will work, then everything is fine till the next morning. I sent it to a small garage but they found nothing.

I recently bought a 1992 Celica GT with 250k miles on it. It has a rough idle and a couple other things that may or may not be stemming from the same thing that's causing the rough idle
Like I said, it has a rough idle and there is a bit of jerking sometimes during acceleration. The exhaust makes sort of a "put-put-put" or "chirping" sound at lower RPMs and the frequency of the sound corresponds to the engine RPM. I do know of a couple things that could be causing the rough idle and maybe even the jerking, but I'm not sure about the sound from the exhaust.
The cooling fans are hard wired to the ignition so they run constantly, so when it's cold out like it is right now it takes forever for the engine to warm up. Is there a switch somewhere that they are supposed to be wired through? Where would that be? Also, the previous owner did kind of a hack job of putting on a cold air intake and I think I may be missing some sensors, especially because it seems to burn more fuel than it should. What sensors are located on the air intake, or are there even some in the stock airbox itself? And would this possibly be contributing to the rough idle and the jerking?
Also, I do get some vibrations when stopped at idle so I think I may want to replace the motor mounts.

I have a '99 GT with the 2200 motor. A couple of months ago, it started sputtering around 3000rpm. Over 3600 RPM, runs great. Per my dealer, both cats and o2 sensors were changed. $$$ Did not fix! Local garage found a extremely frayed wire at the crankshaft sensor. There were two EGR codes as well, but were ignored. They changed the wire and the car has ran great for a month. Now it is sputtering again. The garage checked and there are only the same two codes are for EGR issues (I did not write them down). Could it be the EGR? Does it kick in around this RPM?
