What causes the P0420 code on a Toyota Camry?
The P0420 code in a Toyota Camry will often be thrown one of your oxygen sensors are not functioning properly. Typically, the code will be triggered by the upstream oxygen sensor (before the converter). There aren’t usually any drivability issues associated with P0420.
What is the trouble code on a Toyota Camry?
One of the most common trouble codes with all Toyota vehicles is the P0420. This code number references a number that is given to you when you plug your Toyota Camry into a OBDII scanner. It doesn’t matter which model you have, this OBDII code has the same meaning for all of them. P0420 is a OBDII trouble code. The code technically stands for:
Why does my Toyota Camry not pass emissions?

What does the OBDII code P0420 stand for?
P0420 is a OBDII trouble code. The code technically stands for: Catalyst System Efficiency Below Threshold. Your Camry has at least two oxygen sensors, one before and after the catalytic converter. Among the many jobs that oxygen sensors have is they have to measure the emissions levels coming in and out of the converter.
What is the P0420 error code for catalytic converter?
Error code P0420 – or Catalyst System Efficiency Below Threshold (Bank 1) – is one of several trouble codes that fall into the general exhaust system code block. All P042X codes (where “X” can be any number) refer to the catalytic converter and exhaust system.
Where is the P0420 sensor on a car?
P0420 refers to the catalytic converter or – more specifically – the oxygen (O2) sensors before and after it on the bank 1 side of the exhaust system. On most vehicles, there is an O2 sensor both in front (upstream) and behind (downstream) the catalytic converter. Normally, these two O2 sensors will have different readings when the car is running.
What does the OBDII code on a Toyota Camry mean?
Toyota Camry P0420 OBDII Code Defined. P0420 is a OBDII trouble code. The code technically stands for: Your Camry has at least two oxygen sensors, one before and after the catalytic converter. Among the many jobs that oxygen sensors have is they have to measure the emissions levels coming in and out of the converter.
What is the O2 sensor code on a Toyota Camry?
That sensor should generate its own code, but that’s not 100% certain. A repair shop may tell you the code is P0420, which could mean a new front catalytic converter and O2 sensor. You should clear the code and see if it comes back.
What does P0420 mean on a catalytic converter?
Here’s the official definition of a P0420 trouble code: P0420 Catalyst System Efficiency Below Threshold (Bank 1). What the code is telling you is that the catalytic converter has failed an efficiency test. In 99.5% of the cases, this code means that the catalytic converter itself is bad and must be replaced.
What does the p1349 code on a Toyota mean?
The Engine Control Module ( ECM) controls Oil Control Valve (OCV) to make the intake valve timing properly, and, oil pressure controlled with OCV is supplied to the VVT controller, and then, VVT controller changes relative position between the camshaft and the crankshaft. Need more information on how to fix the P1349 TOYOTA code?
What is the diagnostic code for a Toyota?
OBD-II code P1349 indicates a problem with the variable valve timing system in your Toyota.
What should I know about the P0420 Toyota catalyst system?
P0420 TOYOTA Possible Symptoms Engine Light ON (or Service Engine Soon Warning Light) P0420 Toyota Description The Engine Control Module (ECM) monitors the switching frequency ratio of heated oxygen sensors 1 (front O2 sensor) and heated oxygen sensors 2 (rear O2 sensor).
What does a catalytic converter do on a Camry?
Catalytic Converter – A catalytic converter is responsible for scrubbing out as much pollution as possible from the Camry’s exhaust. Over time, they can become clogged. Although, modern catalytic converters are supposed to last the life of most vehicles, it could be there is some underlying problem if it has clogged.
What does a check engine light in a Toyota Camry indicate?
The problem can be specifically diagnosed by use of a code scanner; however, the light can sometimes be triggered by simple, easy-to-fix issues, such as low fuel or a loose fuel cap. A “Check Engine” light on a Toyota Camry may indicate a number of problems with the car’s electrical systems.

What makes the Check Engine light come on on a Toyota Camry?
I have a 2001 Toyota Camry LE, 4 Cyl with 125K miles and I’m going on my fifth (that’s right 5) catalytic converter. I bought the car used from a dealer and a short time later the Check Engine Light came on (42K mi.). The dealer said it was the catalytic converter and replaced it under warranty.
How do you remove the O2 sensor from a Toyota Camry?
Once it does, attach ratchet to O2 sensor, which you’ll use to loosen and then ultimately remove the sensor. If your engine is warm, or to help ensure you don’t accidentally burn yourself, wear a welder’s glove on one hand and then use that hand to actually remove the O2 sensor once you’ve gotten it nearly off with the O2 socket and ratchet.
How to fix a Toyota camshaft code p0012?
How do I fix code P0012 TOYOTA Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. P0012 TOYOTA Tech Notes There is a factory service bulletin for the following Toyota models: 2005-2007 Toyota Corolla
What does it mean when your Toyota says p0441?
The fumes are collected in the canister and eventually injected into the engine through the purge control valve (PCV), where the fumes are burned. When your Toyota’s P0441 is triggered, it usually indicates a bad vacuum switch or a leak in the EVAP system that is preventing fuel vapors from reaching the canister.
What does the code mean on a Toyota p2238?
Because the heat of the heater is conducted through the alumina to zirconia (of the sensor portion), sensor activation is accelerated. The code is output when there is an open or short in the A/F sensor circuit, or if A/F sensor output drops.
What causes O2 sensor positive current code p2238?
Code P2238 is caused most commonly from an internal failure of the heater circuit inside the O2 sensor.
Why does my Camry have a bad O2 sensor?
Your Camry’s oxygen sensors are responsible for helping to keep your engine running at optimal efficiency. The engine management computer uses the data from all of the O2 sensors to keep the air/fuel mixture optimized. A bad oxygen sensor can affect the mixture greatly.
Why is a P0420 trouble code never a bad oxygen sensor?
NOTE: This is why a P0420 trouble code is almost never a bad oxygen sensor — because the ECM has already tested the downstream sensor. If it isn’t responding properly, it will set a trouble code. The same applies to the upstream sensor.
How much does it cost to replace a Camry oxygen sensor?
As a result the engine computer is unable to determine the proper ratio of air to fuel for the engine. Replacing the failed oxygen sensor should correct this concern. The average cost for a Toyota Camry Oxygen Sensor Replacement is between $399 -$416. Learn More
When to reset P0420 code on Toyota Corolla?
Besides the idea that it might be dangerous, it can help to avoid the P0420 code. By the way, if your P0420 code is caused by this, it should reset itself after driving for about 100-200 miles after your next fill-up where the vehicle is shut down.
