DTC P0302 code

The fault codes refer to misfires, P0300 is a random misfire ,anything from fuel injector problems , vacuum leaks , low fuel pressure ,clogged fuel filter . P0302 is a specific cylinder misfire same for P0303 ! # 2 an #3 cylinders . Spark plugs , plug wires , coils or coil , depending on make model an year vehicle an ignition system type ! Testing is the only way to find out the corrections needed . It takes a very good technician to trouble shoot these problems . Your best bet would be to take your vehicle to a qualified repair shop

How do you know the coil pack is bad ? Did you test it , or are you going just by the P0302 - P0300 ? These codes do not mean the coil pack is bad ! Could have a vacuum leak , could have weak fuel pump , partially plugged fuel filter ! The engine could have a mechanical fault , burnt valve , bent valve , bad head gasket ! Sounds like you need stop wasting your money an take it to a pro !

A code P0302 may mean that one or more of the following has happened:Faulty spark plug or wireFaulty coil (pack)Faulty oxygen sensor(s)Faulty fuel injectorBurned exhaust valveFaulty catalytic converter(s)Running out of fuelPoor compressionDefective computerPossible Solutions
If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). 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.

Hi there:
Misfire #1 or #2 cyl means DTC P301 or P0302 fault code.

All fault codes can be checked out at http://www.bluejag.co.uk but here are the results for some of yours. You can ignor P1111. Looks like a faulty plug or coil pack cylinder 2

Fault Code:- P1314 Indicates a Power-train fault


The fault is generally due to a problem in the Ignition or Misfire area


Fault Description: Misfire rate catalyst damage -bank 2 NOTE: This DTC will flag only when accompanied by an individual cylinder misfire DTC: P0300 - P0306

Action of ECM:- ECM Default:- Maximum engine speed reduced


After clearing the DTC, complete the Misfire monitor drive cycle
Check for a reoccurrence of fault DTC.

Possible Fault:- Cylinder compression low Worn camshaft / broken valve spring(s) Fuel delivery pressure (low / high) Fuel injector(s) restricted / leaking Fuel injector(s) continuously open Fuel contamination Fuel injector circuit fault(s) (Injector DTCs also flagged) Spark plug failure / fouled / incorrect gap ECM to ignition coil primary circuit fault (Cylinder misfire detected DTC also flagged) Ignition coil failure
Fault Code:- P1316 Indicates a Power-train fault


The fault is generally due to a problem in the Ignition or Misfire area


Fault Description: Misfire excess emission NOTE: This DTC will flag only when accompanied by an individual cylinder misfire DTC: P0300 - P0306

Action of ECM:- none


After clearing the DTC, complete the Misfire monitor drive cycle
Check for a reoccurrence of fault DTC.

Check for a reoccurrence of fault DTC.

Possible Fault:- Refer to P0300 Possible Causes

P0302 is a misfire in cylinder #2. When was the last time you changed spark plugs? That's the most common cause of a misfire.

The p0300 What does that mean? Basically this means that the the car's computer has detected that not all of the engien's cylinders are firing properly.
A P0300 OBD DTC code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-
==================================
The p0430 What does that mean? Basically this means that the O2
downstream of the catalytic converter on bank 2 is detecting that the converter is not working as efficiently as it should be (according to specs). It is part of the vehicle emissions
system.

make cranshaft gear has not spun under timing cover ive seen it happen before
