2006 Ford Crown Victoria Ignition Coil Packs

 

The 2006 Crown Victoria remained unchanged. They all came with the 2v 4.6L V8 and used the DG508 ignition coil. This included the CVPI and P71 as well. If there is  bad ignition coil in your Crown Victoria, and the rest are original or over 7 years old, it's best to replace all 8 at the same time. At Araparts, you can find the full set of 8 for the price of one at the local parts stores and dealers. Many of our customers will ask up "why are your parts so cheap? Are the bad quality?". Our parts are the same or better quality as the parts you see at the local stores. The reason why is because we buy from the same manufacturer that they buy from, but instead of distribution our parts to warehouses, who in turn sell to the auto parts stores, we sell direct to you. This effectively cuts out the middle man and leaves more money in your pocket for the same parts that would normally cost over $500. We not only want you to save money on the parts themselves, but on the diagnosis and replacement as well. 

 

How To Diagnose a Bad Coil Pack on You 2006 Ford Crown Victoria

 

First things first, get yourself an OBDII scanner. If you plan on doing any work to your vehicle and you don't own one, you will be blindly throwing parts at your Crown Vic. These cost under $10 at so many retailers online (we also plan on offering these as well in the near future). There is also a different type of OBDII scanner with "Mode 6" capabilities. Mode 6 allows you to see everything the PCM (Power Train Control Module aka main computer) sees. These Mode 6 OBDII scanners start at around $50 online. This may seem much, but it's nothing compared to the amount of money a single diagnostic will cost. We will get into Mode 6 later on if it's needed (aka misfire, no check engine light). 

We will start with scanning a check engine light for any codes. Turn the ignition in your 2006 Crown Victoria to the ON position. Lights on the dashboard should be ON, and the engine should be OFF. Plug the OBDII scanner into the port which is located underneath the driver's side of the dashboard (near the steering column). One you plug it in, follow the directions on the scanner (some will automatically start scanning). If you get one of the following codes there you have narrowed your problem down:

P0301 (Cylinder Number 1 Misfire Detected)
P0302 (Cylinder Number 2 Misfire Detected)
P0303 (Cylinder Number 3 Misfire Detected)
P0304 (Cylinder Number 4 Misfire Detected)
P0305 (Cylinder Number 5 Misfire Detected)
P0306 (Cylinder Number 6 Misfire Detected)
P0307 (Cylinder Number 7 Misfire Detected)
P0308  (Cylinder Number 8 Misfire Detected)

 

Here is an illustration of the cylinder numbers on your 2006 Crown Victoria. From here we are not sure if the cause of the misfire in your 2006 Crown Victoria is an ignition coil or something else, but at least we know where it's coming from. Now remove the ignition coil from the misfiring cylinder with a 7mm socket, and swap it with a coil from a different cylinder. It can be any cylinder. Now reset the computer with your scanner. You can also do the same thing by unplugging the battery for one minute. Drive your Crown Victoria around until the check engine light comes back on. Re-scan. If the code follows the bad ignition coil, then you know what your problem is. If the code remains, then it could be something else like a bad spark plug, fuel injector, damaged wiring harness or something else. From here you can change all of the coil packs in your 2006 Crown Victoria. All you need is a 7mm socket, extension, and ratchet to do this job. A swivel socket can come in handy, but it's not needed. The fuel rail also does not need to be removed to get the coil packs off. Once you unbolt the ignition coils, you will be able to bend the coils over a little bit and slide them out.
