What is the OBD II fault code P0420?
OBD II fault code P420 is a generic code that is defined as “Catalyst System Efficiency below Threshold Bank 1”, and is set when the PCM (Powertrain Control Module) detects that the catalytic converter on bank 1 is operating below a minimum allowable efficiency threshold.
What does Honda catalytic converter code P0420 mean?
The function of the catalytic converter is to break down harmful pollutants that are created by your Honda during the combustion cycle and convert them into harmless gases. Code P0420 indicates that the catalytic converter is not functioning efficiently, therefore increasing the output of harmful pollutants by your Honda. Honda P0420 Symptoms

What does the code p0171 mean on a Honda Accord?
Accord P0171 Code Defined. P0171 is an OBDII trouble code. The code technically stands for: Fuel Trim System Lean Bank 1. The code is thrown when the oxygen sensors detect that there’s not enough oxygen in the exhaust system. This is commonly referred to as a “lean” condition.
What does OBDII trouble code P0420 stand for?
P0420 is a OBDII trouble code. The code technically stands for: Your Accord 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.
When to use lean condition code p0171?
Combustion engines run most efficiently when they maintain an air-fuel mixture ratio of 14.7 parts air to 1 part fuel. When there are more than 14.7 parts air to 1 part fuel in the air-fuel mixture, a lean condition exists and code P0171 is triggered.

What to do if your air filter is p0171?
Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. If the P0171 is combined with the P0174 code, it’s very likely that the problem is caused by an intake leak. If there are no intake leaks, the next step is to replace the air filter and clean the air flow meter.

P0171 HONDA Tech Notes If the P0171 is combined with the P0174 code, it’s very likely that the problem is caused by an intake leak. If there are no intake leaks, the next step is to replace the air filter and clean the air flow meter. If the problem persists the front oxygen (O2) sensor may need to be replaced.
What does lean fault code p0171 mean on a car?
Your car or truck has either a P0171, P0174 lean fault code or both stored in the pc, these codes derive from Oxygen Sensor (O-2) readings. A lean code or codes suggest that there surely is too-much air in the exhaust.
How much does it cost to repair a Honda p0171?
Please try again later. The cost of diagnosing the P0171 HONDA code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
What does code p0171-system too lean mean?
Code P0171 – System Too Lean: Symptoms, causes, common problems, diagnostic. The OBDII trouble code P0171 – System Too Lean (Bank 1) means that the engine air-fuel mixture is too lean, or there is too much air and too little fuel.
What causes the code p0171 on 2002 Toyota Corolla?
Q: What could cause the code P0171 on 2002 Toyota Corolla? A: In the 2002 Corolla, the code P0171 is often caused by a bad or dirty mass airflow sensor or vacuum leaks. Your mechanic can check for vacuum leaks and test the mass airflow sensor with a scan tool.
When these adjustments become too large, code P0171 is triggered. Vacuum leaks – PCV hose, vacuum hoses, intake manifold gasket. It is okay to drive your Honda with P0171 for a short period of time, but driving with this code for an extended period of time can overheat the engine and cause internal engine damage.

What causes a Honda Accord to misfire at idle?
Misfire – If the air fuel mixture has gotten too far from factory specs, this can cause the Accord to misfire. Idle Issues – With the air/fuel mixture altered, the vehicle can idle erratically as the computer compensates to keep the engine running.

What are the symptoms of a p0108 DTC code?
Symptoms of a P0108 DTC code may include: MIL (Malfunction Indicator Lamp) will likely be on Engine may run poorly Engine may not run at all Fuel mileage may decrease Presence of black smoke at exhaust
To keep the engine running properly, the powertrain control module (PCM) tries to compensate for the lean condition by injecting more fuel to the mixture in an effort to maintain the proper 14.7:1 ratio. When these adjustments become too large, code P0171 is triggered. If playback doesn’t begin shortly, try restarting your device.
What does the lean condition code p0171 mean?
What Does P0171 Mean? Combustion engines run most efficiently when they maintain an air-fuel mixture ratio of 14.7 parts air to 1 part fuel. When there are more than 14.7 parts air to 1 part fuel in the air-fuel mixture, a lean condition exists and code P0171 is triggered.

What does p0171 and po174 mean?
A continual low voltage reading indicates a lean fuel mixture, too much oxygen. The optimal ratio is 14.7:1 (air:fuel). When your powertrain/engine control module receives a reading that indicates there’s too much oxygen and the ratio is incorrect, it sends an error code P0171 or P0174.
When does AutoZone send an error code p0171?
The optimal ratio is 14.7:1 (air:fuel). When your powertrain/engine control module receives a reading that indicates there’s too much oxygen and the ratio is incorrect, it sends an error code P0171 or P0174. Depending on the problem, it may send both codes if the issue is causing a lean condition on both engine banks.
How to Fix P0171 and P0174 While inspecting the intake boot thoroughly, another option is to stop at the MAF sensor itself. MAF sensors can get dirty or oiled and send out a false signal, but usually this is also indicated by a MAF trouble code as well.
