Honda Odyssey - Recent Questions, Troubleshooting & Support
I am getting 13 miles per gallon. what is wrong?
Your O2 sensor (or oxygen sensor) is located on your exhaust system. One placed before your coverter to measure the efficiency of the combustion in your engine by measuring the amount of oxygen left in the exhaust stream. The second O2 sensor is placed after the converter and its job is to measure the effiecency of the converter in filtering out harmful gases in the exhaust by compairing its reading to the sensor paced before the converter. If your O2 sensor has failed it will tell the car's computer that it is running too lean (more air than fuel) by default. Since the computer thinks the car is running lean, it now is adding more fuel to the mixture to try and compensate for the lean condition and will always have a check engine light on. If there is no check engine light on then it probably is not a faulty O2 sensor. Have a qualified technician run a fuel consumption test and go from there.
My 2006 honda Odyssey will stall out or just shut completely down or off while in full motion driving.
All engines move back and forth. Sometimes too much:)
Check your motor and trans mounts to see if they are allowing the engine to move too much. You need 2 people to do this: One person on the side of the vehicle with the hood open and another in the vehicle, E Brake applied!!!, carefully shifting from Drive to Reverse. Watch the motor & mounts for movement. If you see much movement, you probably have a weak wiring connection that disconnects when the engine is in a certain position. A short or grounded wire could also be the problem so make sure no wires are bare in certain spots from rubbing as the engine moves.
Check the wiring harness by moving the wires by hand while idling your car. In PARK with the E-brake applied!!! Move the wiring and hoses around, shake them and see if you can replicate the problem in your driveway.
Good luck.
1997 Honda Odyssey. To replace the speedometer sensor is it the counter or main shaft sensor please?
on old cars, not told, fully you, if a/t or m/t box, auto or stick?
but on cars the sensor is named VSS, and is on tail of transmission output shaft ,.
on newer cars with ABS , abs 4 sensors are used at 4 wheels.
no engine told or transmission there.
no vin told.
vss is speed of axles turned by the transmission and is never ever and input shaft. sensor.
we can not see under your hood or behind the flywheel, at all
in the blind.
the SM shows it has 3 pins VSS so is not ABS
has power to it so is HALL sensors (very reliable)
if you scan the PCM (USA onlY) It will tell you it is bad if is.
PCM uses it, and cluster and cruise box. all 3.
sm qoutes
4 cylinder engine automatic.
Disconnect the Vehicle Speed Sensor (VSS) wiring harness. The VSS is located on the rear of the transaxle case near the cooler line inlet.
no engine told not told is an automatic,
me not tossing coin 4 times sorry

The passenger side
The driver's Multiplex Control System is a small computer that controls (among many other things) the dash lights brightness, ignition key interlock, shift interlock, and has a tie in to the brake light system and horn relay. It may be that this small computer malfunctioned and started the whole problem chain.
However, I note from the factory shop manual that if polarity is reversed on the shift interlock--it can be damaged. Reverse polarity will ruin the diode inside the shift interlock. This could have happened when you jumped the battery--a brief period of getting the cables and terminals mixed up could have done it.
Checking the shift lock solenoid can be done by removing the steering column upper cover. Disconnect the shift lock solenoid connector (2 terminals). Using long jumper wires, apply battery voltage to terminal 1 (yellow wire side) of the solenoid and ground terminal 2 (green wire side). Check that the shift lever can now be moved out of Park. NOTE: applying voltage in the opposite direction of that above will damage the diode in the solenoid and will probably ruin it. Remove your jumpers and shift back to park and check that the solenoid locks. If the solenoid does not work properly, it will need to be replaced. This involves removing the end of the transmission shift cable and is a complex job. Remember, no power to the solenoid equals a locked solenoid--it takes power to unlock it.
The Multiplex Control Unit has a self diagnostic feature which checks the computer itself and inputs to the computer. The computer check is called mode 1 and the input test is mode 2. The diagnostic trouble codes are outputted to the ignition key light and beeper.
To test, first confirm that all fuses are good, especially fuse 9 (10A) in the driver's under dash fuse box (left kick panel) and fuse 13 (7.5A) in the passenger's under dash fuse box (right kick panel). Then use a jumper wire (a wire with small alligator clips on each end works best) to jump the two leads of the multiplex test connector. (This is a light green 2 terminal connector dangling from the same wire bundle as the brake pedal switch connector.) Buckle the driver's seat belt (avoids nuisance beeps). Now turn the ignition switch to on. After about 5 seconds, the ignition key light should come on and the beeper should beep for 2 seconds then stop for .2 sec. then beep once for .2 seconds. This indicates that the system is in diagnostic mode 1.
If no diagnostic trouble codes (DTC's) are present, the key light and beeper will not blink/beep again. If there are codes: about one second after entering mode 1, the key light and beeper will indicate the DTC and repeat it every 3 seconds. If there are more than one, the system will indicate them in ascending order. The codes will be a light flash and beep so you will have to count the flashes/beeps to keep track. The codes range from 1 to 6. Code 3 (three flashes/beeps) indicates a problem with the multiplex control unit itself. Write back here for other codes or for questions about mode 2.
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?
Which way do you turn the crankshaft pulley bolt to loosen it?
It turns left (counterclockwise) to remove. An impact wrench is best if you can get one on it.
If you don't use an impact wrench, you may need to somehow keep the crank from turning when you loosen the bolt.
One way is to pull the belt tighter to put more tension on the crank pulley.
There are other creative ways I've used. If you have any trouble let me know.
Honda Odyssey 2007 cruise control, horn, keyless entry stopped working all together at one time!!
There could be a fuse or relay issue since multiple systems became inoperative simultaneously. I'd suspect that when the alarm went off, someone targeted and disabled the horn system so that it wasn't honking inside the repair facility. Both the horn switch and cruise control switch are located in the steering wheel and therefore they share common components and circuitry. Try checking under-hood fuses #7 (7.5A), #13 (20A), #15 (40A) and #20 (40A), as well as under-dash fuses #7 (7.5A) and 21 (7.5A). If all these fuses are OK, much deeper diagnosis will need to be performed. One somewhat common failure item is the spiral cable (also called a clock spring) that transfers power to the steering wheel (while allowing it to turn). That part can be seen within the steering angle replacement procedure shown here: https://www.yourmechanic.com/article/how-to-replace-a-steering-angle-sensor-by-marvin-sunderland
