What causes p2195, p2177, and p0174 codes?
For example, on a bunch of Ford vehicles, the hose that goes from the PCV to the throttle body can melt causing P2195, P2197, P0171, and/or P0174 codes. If a vacuum leak is determined to be the problem, it would be prudent to replace all vacuum lines if they are getting older, becoming brittle, etc.
What causes a p2195 code on a DTC?
For this DTC, the malfunction indicator lamp (MIL) will illuminate. There may be other symtoms. Potential causes of a P2195 code include: Oxygen (O2) or A/F ratio sensor or sensor heater malfunction Open or short in O2 sensor circuit (wiring, harness) Fuel pressure or fuel injector problem Intake air or engine vacuum leaks

What does p1684 mean on a Dodge Ram?
P1684 indicates that the memory has been cleared within the last 50 ignition cycles and does not indicate a problem. Done indicates that NO DTCs are present. Ho2S = heated oxyen sensor, TP = throttle position, MAF = mass airflow, MAP = manifold absolute pressure, TC=turbocharger.
What does the number p0304 mean on an engine?
What Does P0304 Mean? P0304 indicates that cylinder number 4 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 causes a random P0300 trouble code?
In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I’ve also heard in other cases the problems were faulty fuel injectors. Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code.
What does DTC code P0300 stand for?
Code P0300 stands for “Random or Multiple Cylinder Misfire Detected.” This diagnostic trouble code (DTC) indicates that your car’s computer has detected an engine misfire that’s random and/or appearing on multiple cylinders You should never ignore engine code P0300 because misfires can result in very expensive repair costs.
What does the last number in p0302 mean?
The last number in these accompanying codes refers to the affected cylinder. A P0302, for example, indicates a misfire on a particular cylinder (in this example, cylinder 2). Cylinder number 2 would refer, not to the second cylinder in the firing order, but the cylinder numbered “2” in the arrangement of cylinders on the engine.
