The code reader should tell you what cylinder it is if so switch the injectors around to see if the misfire moves to a different cylinder if it does you have a bad injector

My Nissan Maxima is showing code P1335 Manufacturer Controlled Ignition System Or Misfire. Where is this and how do I fix it?


DTC P1335 is not a ignition code. It is for the crankshaft position sensor. You will most likely have to replace that. symptoms sound like the crankshaft position sensor.

Code 340 is a cranking code for the cam sensor that's not working and the1391, it shows intermittent signal. Check the connections and change sensor, make sure it doesn't touch the cam. If your belt is old you should check it too. Good Luck

Random multiple misfire P0300, P0302, P0304 on 2006 Kia Rio


A competent mechanic will check all probable causes associated with these DTC codes.
Code P0300: Random-Multiple misfire detected. Probable causes:
1. Vacuum leaks, damaged hoses, or improper routing
2. Fuel contamination
3. Ignition system - Ignition module, coil, spark plugs and wires
4. Fuel system
Code P0302: Cylinder 2 misfire detected. Probable causes:
1. Control unit software in need of updating
2. Faulty PCM or ECM
3. Faulty fuel injector
4. Ignition system
5. Fuel system
Code 0304: Cylinder 4 misfire detected. Probable causes:
1. Control unit software in need of updating
2. Faulty PCM or ECM
3. Faulty fuel injector
4. Ignition system
5. Fuel system

Be sure the invoice enumerates all of these probable causes as having been checked. Also, some of the replacement parts installed earlier may be faulty.

I HAVE LINCOLM LS AND HAVE THIS CODES P2104 2107 2110 2112 SO ITS THE THROTTLE BODY PROBLEM?


Those codes are commonly caused by a faulty ignition coil "spiking" the throttle control circuits. You need to check for cylinder misfires - fix the misfire and you will most likely fix the throttle body codes.
Other than this, all I can say is that these circuits need to be diagnosed using the troubleshooting charts provided by the manufacturer and the proper equipment to perform the required tests.

Getting codes P0341, p0300, p0301, p0302, p0303 on my 2001 audi a4 2.8 quattro, how do i fix this


Hello! The Trouble codes are pointing at ONLY cylinders 1-2-and 3 (P0301, P0302, and P0303)...P0300 is telling you Random Misfires...P0341 is pointing at the Camshaft Positioning Sensor A (Bank One)...When you face the front of the engine, the Left Bank are cylinders 1, 2, and 3...Although TSB's are written for this problem that isn't much help since you'll pay for it anyway...

The solution is to replace the Camshaft Positioning Sensor A...Of course, check its connector first for bent, dirty or broken pins...Buy a can of Electronic Contact Spray and clean both male and female ends of the connector before buting a new sensor....Follow procedure below...Push two safety pins into the rear of the connector on the specified pin #'s...See diagrams below....Saailer

  1. Connect a Digital Volt Meter to measure voltage across the CMP connector terminals 1 (B+) and 3 (Ground).
  2. Switch ignition to "ON", but Do NOT start engine.
  3. Measure voltage between terminals 1 and 3 . There should be a minimum 9.0 volts.
  4. Switch the ignition "OFF".
  5. If reading is not 9.0 volts replace the sensor...
  6. You'll have to remove the timing chain to replace it...
any questions send a comment...Guru...Saailer

What is scan code P1399 and how to fix the problem.


P1399- Manufactures control Ignition system OR Misfire

If only one of your cylinders was misfiring, you probably would be getting a more specific code than P1399.
Also check the distributor rotor along with the cap and coils and wires; the EGR valve to make sure it doesn't leak; your fuel pressure which can cause random misfires if the pressure is too low; and injectors if they are really dirty. If you have really high mileage, I probably would first just change out the plug wires with a new set, then reset the DTC and see if the code comes back.

What is code 1614 and how do i fix it??


code 1614 means Manufacturer Auxiliary Inputs and Auxiliary Outputs, is also a generic code for a problem with the Evaporator Solenoid Control Circuit . This means that you may have two main problem or more. Your Solenoid Control Circuit or Misfire problem. Check your misfire first. Because misfire can destroy the catalytic converter. Most of the time when you have a misfire under a load condition, such as traveling 35mph+ while adding more throttle, your ignition system is usually the cause. Probably your plug wires are worn out or you may have a leak that will cuase your ignition problem. Here are the basic common questions Ideas. First you need to analyze the situation. If the engine won't crank, you are probably dealing with a starter or battery problem. Has the starter been acting up? (unusual noises, slow cranking, etc.). Is this the first time the engine has failed to crank or start, or has it happened before? Have the starter, battery or battery cables been replaced recently? Might be a defective part. Has the battery been running down? Might be a charging problem. Have there been any other electrical problems? The answers to these questions should shed some light on what might be causing the problem. If an engine cranks but refuses to start, it lacks ignition, fuel or compression. Was it running fine but quit suddenly? The most likely causes here would be a failed fuel pump, ignition module or broken overhead cam timing belt. hope this will help you good luck. if you need more imformation you can email me at reginestacio@yahoo.com . P.S. also check your fuses or sensors this might also cuase the problem.

Glad to help,
Reginskie..
