Having problems with your 2002 Toyota Camry ?
Check eng light trouble code PO420 bank 1 on toyota camry 2002 le
replaced top oxygen sensor reset codes and check eng. light came back on.
My 2002 Camry V6 is having some issues. Went in for an oil change that turned into a front struts, springs and mounts job. Then I was having some problem in the higher speeds waiting for the car to shift, so had a tune up done, which meant new spark plugs, and of course, the gasket! So now I am out about 1K and now the check engine light comes on. Had it checked out and and a catalytic code came up. They fiddled with it and got the check engine light off, but now the VSC and TRAC OFF lights are on. What does all this mean? Should I take the plunge and get the cat converter done now?
More often than not the Cat is bad. Replacing the sensors is the easiest move. Reasons for the cat to go bad will be related to something else wrong with the fuel management and emissions systems in the car, improper sealants or chemicals used on prior repairs causing damage to the cat

Check engine! 2002 Toyota Camry- Auto Zone gave me a code P0420. What does that mean? Do i need to replace the oxygen sensor or the catalytic converter Check engine light came on. Using my scanner it reported code P0420. I reset the Check engine light. Is this okay to do? If something really is wrong and this was just a one time error will the light come back on if it happens again? I checked and the gas cap was loose.

Have a 1996 Isuzu Trooper LS, check engine light came on so I checked it with a scanner and it said generic code PO 133, which is a slow response, or slow switching so I put an oxygen sensor on, check engine light stayed off for a while, but then came back on with the same code. Would the map sensor or any other sensor make this code show up.
I had the same thing. It is something to do with emissions apparently. I was told to check the fuel cap ! I put some silicone on the seal, cleaned it up, put it back on with the correct number of clicks and after about 15 minutes of driving, the C ... 1996 Isuzu Trooper

Mass Air Flow sensor! Just remove your air filter cover. Go to Auto Zone and purchase some solvent. Spray past the air filter and it should correct the problem. If not, replace the Mass air-flow sensor. This is commonly mistaken for an oxygen sensor. ... 2000 Toyota Corolla

Had OBD2 codes P0441 & P0446 on my 1999 Toyota Corolla. Replaced the VSV CHARCOAL EVAPORATORE, disconnected the battery, check engine light went out. came back on this am, took the car to advanced auto & rechecked. The P0441 & P0446 codes were gone, but had a P0125 code showing. Reset & the lights out now. The guy at advanced says that lots of times other sensors will get tripped and it should stay out now that we reset, but not real sure what a P0125 code means or how to fix if light comes back
According to my 2002 Toyota Tundra manual (and it may be different for your car) P0125 is as follows:Insufficient Coolant Temperaturefor Closed Loop Fuel ControlThis would seem unrelated to your original problem. ... 1999 Toyota Corolla
Always had a problem with 2006 grand prix GXP 5.3L V8 "using" lots of oil. This weekend check engine light came on, tech told me it was an oil pressure error. Added about 1.5 pints, reset the code, but it came back on later in the day. Hubby took it back in, resest the code , but light came back on. Tech said its either the oil pressure sensor or the oil pump. Engine is NOT knocking or sounding like its about to break down...how do i know what the problem is? I can't afford to fix both...

The car failed Emissions test. It was discovered the Oxygen Sensor Circuit - DTC 44 (code) was defective. When the ECM was replaced, the car passed Emissions testing. I drove the car home and then to work the next day which was a total of 14 miles. When I was ready to turn the car off, the check engine light came back on. I brought the car back and the ECM had to be replace again. Once again, home and to work (14 miles) and the check engine light came back on. The ECM has to be replace ag

The check engine light came on in my 1995 Nissan XE 4 cyl pickup and I took it to the shop. They said it was the O2 sensor & Wanted 385.00 to replace it. I went to autozone and got one for 20.00. Also replaced the plugs and plug wires. Disconnected the battery cables to reset light but it came back on. 1. What would be the next step now that the O2 sensor has been replaced? 2. Where is the computer located to see what codes come up now? 3. What are the codes for the 1995 pickup?
I would recommend you have Autozone lookup the code on your vehicle, and then report back here with the code. Here is a list of the Generic Codes: http://www.obd-codes. ... 1995 Nissan Pickup

Code 135 is for a faulty heater in the O2 sensor. Since you have replaced the sensor the problem is probably the circuit or the power source for the heater.You'll need to check the heater circuit next. ... Cars & Trucks
The knock sensor on my 2000 honda civic came on. the shop tested and reset the sensor. it came back on the next day so they did more testing and ended up replacing the sensor. On the drive home that night the light came on again with the same knock sensor code. they looked at it again today checked all the wires/sensor and couldn't find any problem. They are now saying we need to replace the whole ecm. just wondering if you can think of anyother solutions?
OK let us assume the knock sensor and ECM are working as they should. The knock sensor is detecting a mis-fire event. Remove the plugs (please note the order by numbering them) and examine them. Do they all look the same? or does one look odd like ... Honda Civic

My 2005 chevy silverado 4x4 check engine light came on. It went on after a hard 4x4ing in deep water. I have a programmer and ran diagnostic. Sys too lean Bank 1 and Bank 2. MAF sensor was also a problem but I noticed my K&N was filthy so i cleaned it and reset codes. Engine light came back on but only the sys too lean Bank 1 and Bank 2. Curious if it may actually be the MAF or possible a couple 02 sensors.
