Numerous causes could of caused these codes:


P0316 Computer detects a cylinder missfire (first 1000 RPM). The possible causes are damaged sensor, ignition syestem, fuel injectors, running out of fuel, damaged PCM or pour fuel quality.


P0302 Computer detects your cylinder #2 not firing properly. The possible causes faulty spark plugs, faulty coil, oxigen sensor, fuel injector, faulty exhaust valve, fault catalytic converter, poor compressor or faulty computer.

What are the probable causes of DTC P0316?


The P0316 DTC code is a generic code that applies to all vehicles. This code means the powertrain control module (PCM) has detected a misfire shortly after startup, specifically within the first 1,000 revolutions. This code may also be triggered with another of the other misfire codes which are P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307, P0308, P0309, P0310, P0311, P0312. If you have another misfire trouble code also, you should diagnose and repair that code(s) first. Symptoms Symptoms of a P0316 DTC may include: MIL (Malfunction indicator lamp) illumination Rough engine start or idle Potential Causes Potential causes of this misfire code may include: Damaged or defective Crankshaft Position Sensor (CKP) CKP sensor wiring or connector fault Poor fuel quality Ran out of fuel Ignition system malfunction Fuel system malfunction: injector or fuel pump Mechanical engine problem Damaged PCM Possible Solutions First off, you'll want to repair any other misfire DTC codes if present prior to diagnosing this code. If you own a Ford vehicle and you have a P0316 along with one of the other misfire codes, you should check for appropriate TSBs (technical service bulletins), as there are some TSBs that in part involve reprogramming the PCM. Doing that requires specialized equipment. Some Ford vehicles even needed a new cylinder head as a result of the valve. Regardless, if you have a Ford with multiple misfire codes including this one, check for TSBs. If the P0316 is the only code, then it's time to do a bit more diagnosing of the crankshaft and camshaft position sensors, and their associated connectors and wiring. A tip we've found is "Since this code indicates a start up misfire, pay attention to items which may expand or contract when cold (if the code sets when the engine is cold), or hot (if the code sets on a hot restart)." Realistically, the freeze frame data from the PCM will be helpful in tracking down the problem. As will a good DVOM (digital volt-ohm meter), so you can perform tests on the wiring and the sensors.

2003 ford focus codes p0316,p0300,p0302,p0303


I had a similar problem with my '02 Focus. I found the actual wires leading to the harness had broken. From the codes I would say you have lost a good connection with cylinders 2 and 3. My Focus started to hesitate and jump until normal temps were reached. Then it jumped and hesitated all the time. I went to the junk yard and got a replacement wire set for $3. I cut the current ones out and used heat shrink and electrical tape to reconnect the new. Worked like magic.

Here is an excerpt from the code problem below. Good luck

- Ignition coils harness is open or shorted
- Ignition coils circuit poor electrical connection

Po316, po 300, po301, po305 2004 ford freestar


These codes are making me lean towards the ignition coil pack.My stepson's 2001 Sable 3.0 v6 had one cylinder misfiring(5-code P0305),which shares a coil with cylinder 1(code P0301).I diagnosed it by trading wire 1 and 5 at the coil,and the code changed to P0301.You have codes for the two cylinders on the same coil,so this is most likely it.(these codes would also trigger P0300(Multiple Misfires Detected) and P0316(Misfire Detected First 1000 Revs)).

2004 ford explorer sport tracs cylinder 1 misfire


The coil-on-plug. These are common to fail. #1 is easy to get to, all you need is a 7mm socket, an extension, and a ratchet. P0301 tells you that cyl.#1 is not firing everytime it is asked to, P0316 means that during the first 1000 revolutions when you start your truck, there was a misfire. To be sure about the coil, swap the coils with the one next to #1. Clear the codes and wait for the codes to return. If the code P030_ shows up, (P0302 if you swapped it with #2, P0303 for #3, for example) Then remove that coil and get you another!

My car is cutting off every time im going under 1000rpm. mercury sable 2002. codes were p0301 p0302 and p0316 until i changed crank sensor and spark plugs now it says p0316 p0305 p0306.. whats going on?...


Hi

P0305 is misfire in cylinder #5.
P0306 is misfire in cylinder#6.
P0316 is misfire on start up.
Have the plugs on those 2 cylinders, and the 2 fuel injectors checked, also check for spark from the coil on those 2 plug wires.

Please get back to us if you have further query or else please accept the solution.
