Question Answered: obd 0440
September 22, 2012, 05:57 AM
According to Haynes, this code says Evaporative Emmission system. There is a selenoid located on the throttle body. I recently replaced mine same yr. car. I paid $40 on the Internet. Replacement was easy. But, something as simple as a loose gas cap can trigger this code. Under the car is a charcoal cannister and plastic tubing leading gas fumes into the cannister from the gas tank. When you start the engine these fumes are burned along with the regular air/gas mix. My code was PO443 If you look It up It specifically says selenoid. While, your code is very general?

Both are located on the rear bank. The actual configuration is as follows: cylinders 1 is at the rear left corner. then 3, then 5, and 7 is the last on the right end. ALL are in the rear. the even numbered cylinders are all up front. with 2 at the eft end then 4, 6, and finally 8 is on the right end. The front coil pack is easy to remove. The back bank is a bear. Also, there is a set pattern to use to re tighten the bolts as they also hold down the valve covers. Pick up a Haynes repair manual at any auto repair store. About 20 bucks.
Question Answered: MISFIRE #6

I have a 2003 Deville and got exact same code. I replaced the ignition coil bank (front coil pack). Under each are 4 short spark plaug wires. under which are the spark plugs. It may be a good time to replace them If It Is time. The rear bank is a bear to replace. The front bank where cylinder number 6 is located is easy. I used every method od diagnosing with OBDll diagnosis tools. I finally just took a leap of faith and I was right.

Usually located under dash either in the center or in the passenger side. Maybe that's why when you close passenger door it works. Maybe a loose connection?

Try checking prices on the internet. I use Rock Auto .com. I have no affiliation. I use them becasue of quick delivery and good prices. go to or click this link then follow the button and choose your year and make and model. You already know the name of the part so look under cooling or hvac parts.

Question Answered: My heater turns on but wont blow out air what is worng with it?

It seems your saying you can hear the air rushing out of the vents but It is not hot. If that is the case, check your coolant level. If you have a bad thermostat that opens too early, It will keep the water temperature from getting hot enough to go through the heater core and the cold air rushing through the core will not dissapate the heat from the heater core. So, first check you have sufficient coolant in engine. Do not remove the radiator cap when engine is HOT. Check it when IT is COLD the level is clearly marked. If you can feel rushing air with your hand at the vents and It I cold. The remote possibility is the A/C is mixing with the heated air. This would require a shop to check for broken or misaligned parts that control the A/C and heated air being directed through the vents.
Question Answered: What is the estimated cost to replace leaking Air Conditioner return line.
September 22, 2012, 05:13 AM
I cannot give you an exact estimate but I can tell you what is needed to complete this job. Always remember that once you open the A/C system you must first put the system under vacuum. This is how you get the proper amount of freon into the system. Of course refrigerant is a better word as freon was a brand name. A dye can is always a good idea to add when recharging the system. If you have any future leaks It wil be quite evident when using a black light the dye will light up and indicate where the leak is located. Then the refrigerant is introduced under vacuum, about 2-5 pounds depending on the model car. I estimate the hose replacement plus labor and cost of refrigerant is about, $200-$300. If you know which line is leaking call around and ask what estimates are at different repair shops. It could vary by as much as 20-30%. Make sure you can get a warranty on the work performed IN WRITING.
Question Answered: engine light on cod p0443

Your on board computer is telling you that code PO443 is causing this code. you can google the OBDll codes and find this information and what this particular code means. I can tell you (after looking it up myself), It refers to the selenoid that controls the EVAP emission system. To start at the beginning, there is a plastic tube that directs the fumes from the gas tank to a charcoal filter in a canister.This canister is located under the vehicle 1/2 way between the tank and the driver. It can be accessed through an access hole in the trunk. However, the actual selenoid is mounted on the throttle body. I recently urchased one off the internet for $40.00 and installed It myself.Believe it or not, but a simple little thing as small as a loose gas cap can cause this code to appear. The whole idea how it works is to burn the built up gasoline fumes in the tank. Once you start the engine the fumes in the lines will be sucked into the engine and burned. Meanwhile, those not burned are routed through a charcoal canister to be neutralized so they won't pollute the atmosphere. Small plastic tubing tie all these parts together routing the fumes to their proper places. I replaced the selenoid on my vehicle but I am still geting this code. Car runs great so I think It Is erroneous.
