Factors including movement and shape of the object in front of the vehicle, weather and road conditions can all impact automatic brake control and collision warning. This code gets thrown if the reading from the first O2 and the second O2 don't jive. Do you have any suggestions or ideas, or anything else to try in reference to my situation. If this issue is happening only during the warm up period that the vehicle is running, then a P0421 code would be stored. Many thanks in advance to anyone who can help!!! Did you try resetting the computer? I see you have searched and posted about the p0421 code on some other threads.
I was running stage 1 sf+tip like i said it ran fine as soon as i put the internals in yesterday it i turned it off and on like 3 times before putting it away. This time period would be from when the vehicle is first started until about five to ten minutes later. The information contained on this site is presented for informational purposes only. What does that mean and where do I go from here? Thanks for the response Chapper. Do you have any suggestions or ideas, or anything else to try in reference to my situation.
I am in Canada, here Mazda has a 3 year 80k warrenty on bumper to bumper warrenty, thern a 5 year 100km on their powertrain. If the circuit checks out, then consider replacing the sensor. That pretty much says that it is working. Of course they sent the wrong upper gasket. Check engine light came on.
I believe my cat failed because a mechanic installed my new timing belt a tooth off causing the ignition problem. We are not responsible for any actions you take on your vehicle. Install header, and or use the non-fouler trick. If a catalytic converter has melted internal parts, or has been clogged up by carbon deposits, the engine will not be able to breathe properly and will therefore run poorly. Are there any aftermarket options that are cheaper?.
Again, if your car has the same setup as mine, there are 2 Cats. This test monitors the number of high resolution pulses which have been missed not detected. In order for an engine to run well, it must be able to breathe properly. Be aware that these tricks may not be acceptable with your emissions inspection. I believe this is the most common mistake made. I wouldn't expect spark plugs, you would likely have misfires and other codes to support that route.
Requires compatible phone, and standard text and data rates apply. I have a 2014 Mazda 6 iTouring with just under 84k on it. As oxygen storage capacity decreases, the heated oxygen sensor 2 switching frequency will increase. The P0421 code can be very serious. A three way catalyst converter Manifold with high oxygen storage capacity will indicate a low switching frequency of heated oxygen sensor 2. The powertrain control module uses data received from the upstream and downstream oxygen sensors and compares the two readings given.
As I started driving it barely had any power I have a stick so I drove it to a big parking lot where I knew I'd have it towed. The bestthing to do is get in contact with your local Mazda dealer. Also, the Mazda cat had studs to bolt to the front pipe. Then reconnect terminals and see if it starts. This time I drive it all the way into the mechanic since I know it's a misfire.
YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle. Hopefully some one will chime in with some more help. How serious is the P0421 code? I'll try the carb cleaner trick too this coming week and let you know the results of everything. If the catalytic converter has failed and the engine is not running properly, severe engine damage can result from continuing to drive the vehicle. It was completely burned out due to bad ignition coils previously. The first time the shop said that if it came on again, take it to the dealer due to the 8 yr emission warranty. This holds especially true when considering that the catalytic converters are usually the most expensive part of the whole exhaust system.
