What does P0300 mean on a Toyota ECM?
When this code is present in your ECM, your vehicle’s computer has detected that not all cylinders are firing as they should. P0300 indicated a random, or multiple misfires. A misfire code can be triggered due to: This code indicates that a misfire has been detected on engine cylinder 1. Here are the possible causes:
What does the code p0430 mean on a Toyota?
Code P0430 is triggered when the three way catalytic converter, side bank 1, does not operate properly. Most likely, it does not have enough oxygen storage capacity. When this code is triggered, it means there is a fault in the evaporative emission control (EVAP) system.
Can a clogged catalytic converter cause a misfire?
A catalytic converter that is clogged and is restricting the exhaust gasses from leaving the engine can also trigger multiple cylinder misfire. If your catalytic converter is clogged you will notice a drastic drop in fuel efficiency and real struggle getting your Mercedes to accelerate. If the cat is completely clogged your car won’t even start.

What does a P0300 Random Misfire code mean?
A “P0300—Random Misfire” code can make your life miserable. Codes can go from one cylinder to another without a clear pattern. And they may appear for one or more different reasons: And the list goes on. Typically, a random misfire shows up because of an issue with the ignition or fuel system, the ignition timing, or engine compression. 1.
Can a bad catalytic converter cause a P0300 code?
Although rather uncommon, a faulty catalytic converter can cause code P0300 to set. If the catalytic converter becomes restricted, it can create enough back pressure to cause a misfire and trigger code P0300. Can a bad O2 sensor cause a P0300 code?
Can a leaking EGR valve cause P0300 to misfire?
If you find trouble codes, other than P0300, stored in your computer memory, try to fix those codes first since they may be the source of the misfiring problem. A leaking EGR valve can lead to a random misfire. Photo courtesy of Towel401 on Wikipedia.

How can I tell if my car has a P0300 code?
Use FIXD to scan your vehicle to verify P0300 is the only code present. If other codes are present, they must be addressed first. Check for loose connectors at the ignition coils or for damaged wiring. Look for loose engine ground wires as well.
When does a Toyota engine have a trouble code?
This trouble code is usually triggered when the O2 sensor in position bank 1, sensor 1 is bad or has faulty wiring. Replacing the sensor will almost always get rid of the code.
Why does my Toyota engine have a code p0401?
When code P0401 is triggered, it’s because the DPFE sensor found too little recirculation. This code indicates that too much exhaust gas recirculation (EGR) is occurring — the result is an overly-rich mix of oxygen in the air/fuel ratio and higher engine temps.
What is a misfire condition on a Toyota Corolla?
