What does it mean when spark plug is p0304?
If the misfire moved to cylinder number 4 (P0304), then you have determined that the coil pack is faulty and needs replacement. You can do the same test with the spark plug, i.e., move cylinder 5 plug to cylinder 3 and if the misfire is now P0303 then the plugs are at fault.
What causes a misfire in a Ford P0300?
Low fuel pressure can cause intermittent misfires on multiple cylinders. When the pressure is below the specification, the engine does not receive the proper amount of fuel and will start to lean misfire. The fuel pump or fuel pressure regulator could be the source of the low fuel pressure.

What does p0305 mean on a car engine?
P0305 indicates that cylinder number 5 is experiencing misfires. A misfire occurs when an insufficient amount of fuel is burning in a cylinder. The efficient burning of fuel is essential to engine operation as the combustion of fuel is what provides the energy to power the engine.
What does the code p0040 on the Check Engine light mean?
The PCM monitors the heater circuit and will turn on the check engine light if it finds a problem. The code P0040 stands for O2 signals swapped bank 1 sensor 1/bank 2 sensor 1. This is an usual code; it doesn’t come up often. It indicates that the oxygen sensor signals have been swapped.

How does a mechanic diagnose the p0410 OBD-II trouble code?
The Check Engine Light will be illuminated and the code is set in ECM memory and freeze frame. The air injection system pump may be noisy from bad bearings. The engine may run too rich if excessive O2 is being pumped into the exhaust. How does a mechanic diagnose the P0410 code?
What does fault code p0301 through p0312 mean?
If you are reading fault codes such as P0301 through P0312, that means that most likely the problem is with one of the cylinders misfiring. This is due to a bad spark plug, spark plug wire or ignition coil issue. If you are reading a P0301 through P0312 code plus another code, let say P0100.
When does the p0410 O2 sensor fail?
Code P0410 is triggered when the air injection pump passive test fails or is inconclusive then the ECM commands the pump to do an active test and the O2 sensor does not output a higher O2 content in the exhaust within 3 seconds. Need help with a P0410 code?
