Where can I find OBDII check engine light codes?
We have also implemented a new area for posting some responses to our most common code questions, so be sure to visit these pages for some instant info on your check engine light code! These Generic OBDII Check Engine Light Codes are listed numerically and by classification for easy searching.
Why are there so many check engine light codes?
Generic check engine light codes were set up so that there would be a more standardized system of defining trouble codes from all the vehicle manufacturers. Many of the code definitions may seem a bit strange, so don’t be afraid to contact us with any questions regarding definitions.
What are the symptoms of bad spark plugs?
Symptoms of bad spark plug wires include a rough idle, a noticeable drop in engine performance, and lower gas mileage. Expect to spend about $50 for a set of plug wires. The mass airflow ( MAF) sensor monitors how much air enters the engine.
What causes a check engine light to flash?
Many times, P0301 occurs when there are worn-out spark plugs, spark plug wires, or a faulty ignition coil. What Are the Symptoms of Code P0301? Check Engine Light is on Check Engine Light flashing
When does the O2 sensor turn on the Check Engine light?
The engine control module (ECM) sees the voltage of the O2 sensor for bank 1 sensor 2 above 1.2 volts when the ECM has commanded the fuel to a targeted lean condition on that bank of the engine. The ECM detects the voltage high problem and turns on the Check Engine Light.
What is the OBD code for bank 1 sensor 2?
P0138 is the OBD-II generic code indicating the O2 sensor for bank 1 sensor 2 fails to have a lower voltage output below 1.2 volts for more than 10 seconds indicating a lack of oxygen in the exhaust stream.
What happens when the O2 sensor goes bad on a Honda CRV?
Oxygen sensors play a vital role in both engine management and emissions control. When an O2 (oxygen) sensor go bad, it’ll cause your Honda CR-V ‘s engine to run less efficiently. Your CR-V can exhibit symptoms when the Oxygen sensor has gone bad.
Why does the Check Engine light come on on my Honda CRV?
Oxygen sensors can change the way that your CR-V’s engine runs. Most of the time, the check engine light will come on. It’s a good thing that the check engine light would come on, as there is more than one oxygen sensor, and they can be difficult to get to and test.
Can a check engine light be an oxygen sensor?
It seems as though the check engine light and O2 Sensor codes have always gone hand in hand. I can’t even begin to tell you how many perfectly good sensors I’ve seen replaced for a rich/lean code, or as a cure to a service engine light that comes and goes. Fact is, when oxygen sensors were first being used, they did tend to fail.
How can I tell if my O2 sensor is bad?
A combination of the check engine light and one of the other signs may indicate that the o2 sensor has failed. The best way to know for sure is to identify the Diagnostic Trouble Code (DTC) that is stored in the ECU.
Why are there generic check engine light codes?
This is an all inclusive list intended to help you get not only a code definition, but also some information on what could cause these codes and what can be done to repair the related faults. Generic check engine light codes were set up so that there would be a more standardized system of defining trouble codes from all the vehicle manufacturers.
Do you need special tools to reset check engine light?
No special tools required. If you are repairing your car to pass emissions then you’ll need to drive your car around for about 50 miles so the car’s computer can give an accurate reading, otherwise, you’ll be wasting your time and they’ll tell you to come back after driving it around for an hour.

What to use to measure piston to valve clearance?
This is non-hardening clay that molds very easy when it’s warm. Before placing clay on the piston, apply a thin coating of either WD-40 or light engine oil on the cylinder wall to help keep the clay from sticking during the measurement process. Press a generous piece of clay into the two valve reliefs on top of the piston.
What kind of head gasket do I need to check valve clearance?
Each valve receives a light oil treatment to help keep the clay from sticking to the valve face as the crankshaft is rotated. A head gasket with the proper thickness is required to ensure accurate clearance measurements. We used a pre-flattened gasket.
How much clearance do you need for intake valve?
So, how much clearance is enough? A safe rule of thumb is .080-inch for intake valves and .100-inch for exhaust, which requires a little more clearance because of the increased heat factor. Experts also suggest adding .030 to each valve if the engine is equipped with aluminum rods as they tend to stretch more than steel.
What does a faulty check engine light mean?
It helps monitor how much fuel is burned. A faulty sensor means it’s not providing the right data to the computer and causes a decrease in gas mileage. Most cars have between two and four oxygen sensors; the code you get from the scanner will tell you which one needs replacing.
