Question about 2003 Toyota Corolla

1 Answer

What'll happen if I dont fix P0420 code in my 2003 Toyota Corolla

I got a 2003 Toyota Corolla LE as certified used car from Glendale Toyota three years ago. Today, its got around 102500 miles and the CHECK ENGINE LIGHT just came on. I went to autozone and they diagnosed my car resulting to the P0420 code, commonly known as for defective catalytic converter. First how long will my car last without getting my car fixed? And most importantly, what will happen if I don't fix this problem? I heard a lot of people having issues of this problem returning. If I have it fixed, what do I need to do so I don't go through this problem again? Please help. Thank you!

In reality nothings happen, and your saying what do you need to do so you will not encounter this problem again well honestly you cant depend on life on catalytic so i suggest to do your general tune up like changing spark plug,wires,check timing,fuel filter,oil change the way they should be change so it helps the engine burn near stoichiometry because during the oxidation happening in your catalytic if your engine rich or lean or misfiring it could cause a defective catalytic converter.

2001 Toyota Sienna CEL displayed code P1150 & P0420 what could be the problem


Mine is a 2001 Sienna LE. I got the P0420 code and the dealer want to replace an engine control computer for $1600. I've found posts that say you can replace your oxygen sensors, which still costs around $100 each. The P0420 seems to be emissions related. When my check engine light comes on, I run the highest grade, no ethanol gas, and usually within a couple of tanks, the light goes off again. The last time it happened about 2 wks ago, I put in the 93 octane no ethanol premium and a can of Seafoam and within a half a tank, the light went out. Your problem might be more serious, and I don't know what the 1150 code is, but so far that's worked for me.

I have a 2003 Toyota corolla and my car won't


Same thing happened to me. Turned out to be a blown Alt fuse (under the hood behind the battery, you'll have to unbolt the whole fuse box though. That fuse is bolted in from underneath) and a blown am2 fuse (look underneath the dash of the driver side from inside the car). I switched those out and the car started right up

I bought a used 2003 Corolla LE, and it did not come with a keyless remote. Does it have that feature installed? If it has one, how do I get a remote that works? Thanks!


some do and some dont.... you would need to go to toyota and have them run the VIN. If the car was equiped you can get one and have the dealer flash the computer.

I have an engine light on to my Toyota Corolla 2003; diagnosed by the autozone OBD11 SCANNER P420. I replaced the oxygen sensor and the light deleted. After driving the car for 30 miles the light came on...


Hi

The trouble areas associated with this code are as follows:
1)Gas leakage on exhaust system
2)Oxygen sensor
3)Heated oxygen sensor
4)Three–way catalytic converter

The idea is to check for exhaust leaks first then the front sensor and rear sensor. If these all check out then the cat needs to be replaced.

Hope this helps. Thanks for using fixYa
