Question Answered: 

Depending on how the sensor is reading wrong I don't recommend driving it much. There is a possibility of the vehicle causing damage to the catalytic convertors due to it not having the proper fuel / air mix. To replace the convertors will be even more expense for they are not cheep.

Question Answered: 

When you pull both heads on a vehicle to replace the head gaskets the proper way, depending on the mileage of the vehicle, is to have a valve job and resurface performed. Considering the time and expense to do this and again depending on the mileage of the vehicle the shop may be recommending a whole engine due to cost effectiveness and the warranty available with a complete engine. Just doing the heads and gaskets may cause issues with the rest of the engine later. Have the shop explain to you what their advantages are of a whole engine compared to the gasket.

Question Answered: 

It is the fuel gauge or the sending unit. The fuel gauge is on the instrument panel and the sending unit is in the fuel tank. A properly equipped shop can test the gauge but it is difficult to test the sending unit in the vehicle. That being said... The sending unit is most likely the issue due to age. You will need to remove fuel tank to replace sending unit. The fuel pump is attached to the sending unit and we recommend replacing the whole assembly as a unit. This will be a difficult job to do yourself safely due to having to get the tank out from under the vehicle and fuel lines being opened. If you decide to do it yourself do not cheep out on the part. Pay more for the high quality part because you will not wish to do it again.

Test for battery voltage to the sensors heater circuit. If OK then ohm heater circuit. Should be 3-30 ohms. If it's not replace sensor. To replace the sensor use an oxygen sensor socket and with a warm engine - not hot, not cold - remove sensor. Keep in mind... I'm in Florida so I don't have rust issues like you might. You might be better off taking it to a shop incase it needs to be heated up to get out. You don't want to round off the sensor or strip the treads in the exhaust. That will get expensive to repair.

Question Answered: 

Too many possibilities. Low on refrigerant (then whats leaking?), pressure switches (which one?), control head, false sensor reading to computer telling it to turn off. I can go on and on. Take it to a shop and have it diagnosed. It will save you money in the long run to repair the cause than to guess and just put parts in it.

Reset computer... No you won't have to. In my opinion we always go with the factory style and brand of spark plugs. I know on the Odyssey they are not inexpensive but the system was engineered to work with those plugs.

30-Minute Learn Procedure Important: Do not remove the key from the ignition during this procedure. If the key is removed, the procedure will have to be performed from the beginning. Turn ON the ignition, with the engine OFF. Attempt to start the engine, then release the key to ON. The vehicle will not start. Observe the SECURITY telltale. After approximately 10 minutes, the telltale will turn OFF. Turn OFF the ignition, and wait 5 seconds. Repeat steps 1-4 two more times for a total of 3 cycles/30 minutes. The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch transition from OFF to RUN. Important: The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to RUN. You must turn the ignition OFF before attempting to start the vehicle. Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password. With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles.

Question Answered: 

This is a common problem this time of year. You will need to get under the vehicle and look for a short plastic tube coming from the black case at the firewall on the passenger side. Carefully insert a piece of wire up it about 2-5 inches. Most likely you will get a rush of water so you might get wet. If you have a shop you regularly get service done at I'm sure they will clear it inexpensively if not for free.

Question Answered: 

If you get major sparks, like welding, the positive wire to the starter may be touching metal somewhere. Look close... most likely it will be at the starter. Maybe the terminal end turned slightly when tightening it. If the sparks are minor it might be something was left on... headlight, ignition, or something like that. Be careful.
