1999 Honda Odyssey - Answered Questions & Fixed issues
How many 02 sensors on my 1999 Honda Odyssey 6 cylinder van ?
Assuming yours is the V6 engine there is most likely 4 on that vehicle. They are usually mounted before and after the Catalytic converter, (Cat), so there will be 2 in each side of the exhaust system. The O2 sensors closest to the engine are often mounted in the actual exhaust manifold or very near to it. The sensors furthest from the engine are usually underneath the vehicle. Which one are you trying to find?

2005 HONDA ODYSSEY 3.5L V-6 ENGINE FIRING ORDER
For random misfire people it’s easy to check if the valve cover is leaking into the spark plug area thus shorting out the plugs. Pull the coils out and inspect them clean them well, the tips and grommets come off, look for cracks, replace rubber tips that are cracked or have arc burns, clean coils with brake cleaner. Removal of Intake plenum and valve pan covers is necessary to cure the issue, Must clean surfaces and use high-temperature silicone sparingly don’t overtighten, just finger tight and let cure overnight and torque them down after silicone has fully cured. Don’t allow silicone to get into the engine oil by using small amounts and don’t squeeze it all out between the surfaces by tightening it down before curing. Easy as Pi.
Many YoutTube videos on the subject. Allow 4 to 6 hours and don’t rush the job. Never paint spark plugs or they will short out causing a no start due to grounding through the paint!
Good luck! Leave feed back if this helps!

1999 Honda Odyssey will not engage Reverse. Engages all forward gears
Park you car on a level surface. Set the parking brake on you car; start the engine and let it get to full operating temperature; pop the hood and while the engine is running, check the transmission fluid by pulling out the transmission dipstick. Wipe off the dipstick, reinsert it into the dipstick tube all the way down, then pull it out again and check the fluid level.
As you check the fluid level, observe the fluids' color; any discoloration, other than a bright red color, means the transmission is going bad, especially if the fluid smells burnt.
If the fluid passes the visual and smell test, make sure the transmission fluid level is within or between the fill and full marks. If you need to add transmission fluid, make sure you use the right type based on the car manufacturer's specs which are located in your car's owner's manual. In absence of one, call your local dealership or parts store, they can easily look it up free of charge. Of course if the level is low, add a little fluid at a time through the dipstick tube while the car is running- checking the fluid level frequently.
Then check the PCM for any DTCs; are you pulling any fault codes?
If there is damage to the bands, clutches, or solenoids, a tear down and rebuild of the transmission will have to be done; and it is costly

Why is hot air not shutting off when everything is off?
Curious if you mean when the vehicle is shut off?? If your heater fan continues to run with the ignition key off your blower motor resistor is shorted out.. More then likely.. I've done several on Chevys for that concern.

Turns off when put in reverse or drive
First and most economical repair to help or fix this problem- clean the throttle body. Auto parts stores sell an aerosol intake cleaner that'll help, and perhaps fix this problem.
