Freelander p0353 error - 1999 Volkswagen New Jetta

Most are just misfires. Can you remove the spark plugs, clean and check the gap?

It might be getting spark but that spark might be out of the allowed timing signal that triggers it. You can not tell without a scope.

get engine warm and remove each plug lead one by one with nilon plug lead plyers and see witch one makes no diferance to the running and then replace the coil and clear the falt code

The code P0353 is for cylinder #3. (3rd one back from the front of the engine) on the passenger side. Follow this plug wire to the correct coil pack.

P0353 - Ignition Coil C Primary/Secondary Circuit Malfunction
The COP (coil on plug) ignition system is what is used on most modern engines. There is an individual coil for each cylinder that is controlled by the PCM (powertrain control module). It eliminates the need for spark plug wires by putting the coil right above the sparkplug. Two wires are dedicated to each coil. One is a battery feed usually from the power distribution center. The other wire is the coil driver circuit from the PCM. The PCM grounds/ungrounds this circuit to activate or deactivate the coil. The coil driver circuit is monitored by the PCM for faults

If an open or a short is detected in the driver circuit for coil number 3, a P0353 may set. Also, depending on the vehicle, the PCM may also shut down the fuel injector to the cylinder also.

Symptoms of a P0353 DTC may include:
MIL (Malfunction indicator lamp) illumination
Engine misfire may be present or intermittent

Potential causes of a P0353 code include:
Short to voltage or ground on COP driver circuit
Open on COP driver circuit
Loose connection at coil or broken connector locks
Bad Coil (COP)
Faulty Powertrain Control Module

Possible Solutions:
Is the engine misfiring presently? If not, the problem is likely intermittent. Try wiggle testing the wiring at the #3 coil and along the wiring harness to the PCM. If manipulating the wiring causes the misfire to surface, repair the wiring problem. Check for poor connection at the coil connector. Verify the harness isn't misrouted or chafing on anything. Repair as necessary

If the engine is misfiring presently, stop the engine and disconnect the #3 coil wiring connector. Then start the engine and check for a driver signal to the #3 coil. Using a scope will give you a visual pattern to observe, but since most people don't have access to one there's an easier way. Use a Voltmeter in AC Hertz scale and see if there's a Hz reading of between 5 and 20 or so that indicates the driver is working. If there is a Hertz signal, then replace the #3 ignition coil. It's likely bad. If you don't detect any frequency signal from the PCM on the ignition coil driver circuit indicating the PCM is grounding/ungrounding the circuit (or there is no visible pattern on the scope if you have one) then leave the coil disconnected and check for DC voltage on the driver circuit at the ignition coil connector. If there is any significant voltage on that wire then there is a short to voltage somewhere. Find the short and repair it.

If there is no voltage on the driver circuit, then turn the ignition off. Disconnect the PCM connector and check the continuity of the driver between the PCM and the coil. If there is no continuity repair the open or short to ground in the circuit. If continuity is present, then check for resistance between ground and the ignition coil connector. There should be infinite resistance. If there isn't, repair the short to ground in the coil driver circuit

NOTE: If the ignition coil driver signal wire is not open or shorted to voltage or ground and there is no trigger signal to the coil then suspect a faulty PCM coil driver. Also keep in mind that if the PCM driver is at fault, there may be a wiring problem that caused the PCM failure. It's a good idea to do the above check after PCM replacement to verify there won't be a repeat failure. If you find that the engine isn't misfiring, the coil is being triggered properly but P0353 is continually being reset, there is the possibility that the PCM coil monitoring system may be faulty.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Estos codigos se refieren a mal-funcionamiento de las bobinas que suplen el pulso electrico a los espares. Se recomienda que la cambies los coils. El reemplazo lo encuentras en Pep Boys por algunos $120.00 dls.

Hi. Error code P0353 tells you that ignition signal coil 3 primay/scondary circuit is malfunctioning. There are thing to be checked to clear this code. I provided you a link for this.
Error Code P0456 is a diagnostic trouble code pertaining to leaks in the vehicles fuel vapor management system. The code is often set by failure to properly seal the gas cap after filling the tank, or from leaving the engine running while filling up at the gas station. The code can also be caused by a damaged fuel vapor line, a bad seal in the evaporative emissions system, a leak at the purge valve or a leak in the vapor canister. After you have determined the cause of failure and corrected it, you can clear the code out.

bad ground connection for coils or harness is bad for coils
