Question about 1999 Honda Accord

2 Answers

O2 sensor or relay

After driving awhile, less than ten minutes or so, my 99 accord has started cutting off and seems to have to cool or set atleast for anywhere from 20minutes to several hours before it will crank back up only to stall again. ive replaced fuel pump but had a diagnostic done saying to check my o2 sensor and relay. Do both of these need to be replaced and what if that still doesnt fix THIS ISSUE. IM NOT RICH, OBVIOUSLY I DRIVE A 99MODEL.

Hello anonymous,

My personal opinion... you are richer for having had a
reliable HONDA... and we all (the planet) is richer for the effort to keep it running efficiently (thank you).

I believe your new OXYGEN SENSORS will
work just as well as the old ones
(you are WISE to ask)..

It would MOST LIKELY be wasted money.

I suspect that your engine is being suffocated by a
collapsed catalytic converter or blocked by a muffler...

Unless you have changed one RECENTLY you
would be money ahead to consider both to save
on future labor charges... It is not a HORRIBLE
DIRTY job... if you know how to use LIQUID
and don't mind a concussion or two...
(my way of getting smarter).

Check out the costs... (but be VERY AWARE)
Saving $12 on the non C.A.R.B version could be
hideously EXPENSIVE if you live in NEW YORK or
CALIFORNIA (really bad idea)

Hope this helps...

Big savings can be had if you use a QUALITY wrench...
and soak everything up with liquid wrench
(especially on the OXYGEN sensor threads)...

It could be more a relay problem, do you have the code as the code helps better different code reads come up with a generic code and code read will say what the code is but this can differ from what the code actually means, like Code 41 to test the sensor, do this. you will need a meter, Turn ignition off. Disconnect 4-wire connector from O2 sensor. Measure resistance between connector terminals "A" and "B" on O2 sensor. See Fig. 9 . If resistance is 15-20 ohms, go to next step. If resistance is not 15-20 ohms, replace O2 sensor. then this Check for continuity from each terminal of O2 sensor to ground. If continuity exists, replace O2 sensor. If continuity did not exist, check for continuity between O2 sensor terminal "A" and terminals "C" and "D" individually. See Fig. 9 . If continuity does not exist, go to next step. If continuity did exist, replace O2 sensor.
O2 sensor or relay - 192750_ho2s90accord_1-02v24stlnrwd2v1pzef3romw-4-0.jpg there is a heater built into the sensor this heats the sensor to work more efficiently. if the heater is damaged this will not work properly, when the exhaust is up to temp it turns it off but still reads the heater. sensor reading is constant. if this fails the ecu log this as a fault and in USA it cuts the engine out. as there is a fault with reading the sensor. a weak or warong relay will also give a false problem but this is because the connections are not good, sometimes you can repair the relay if its not connecting properly, as the copper heats up and its arcing in the switch it will stop connecting until it has cooled down. you can clean the connections on thew switch inside the relay and adjust the copper arm so its a better connection when the relay is in use. O2 sensor this is not the case it could be damaged and need replacing, also if the weather has been wet and humid there could be a leak in the connector to the main wiring this can be a bad seal on the plug, check this for water and also check the connections inside as if they white this means water has gotten in there clean them with emery cloth to clean them back up to a shine and make a good connection. the relay has 2 plastic tabs that you use to open the relay up, they are in the bottom of the plastic use a flat blade or driver to prise it open. hope this helps.

Sounds like the ignitor in the distributor has gone bad. The cheaper way out is just buying a good used distributor from the bone yard. I've had this same problem several times on these Hondas.

SOURCE: 99 accord stalls out while driving... wait a

Honda Accords are notorious for cam sensor problems. The cam sensor is built into the distributor and is not available as a separate part. The entire distributo will require replacing. I have seen them cause everything from an intermittant misfire to an intermittant stall (as you are describing) to a complete no-start. (requiring a tow truck)

Could bad maf sensor and bad idle air valve have vehicle stall then hard to start for awhile and cuts off after 10 minutes of driving

I would also suspect the ignition module. They tend to work ok for a few minutes when they are cold, then fail once they warm up. If you wait awhile for the ICM to cool down, it will work as well as it can until it warms up again. A code scanner is your best friend to know where to start looking, and to perform tests and log data.

Car cuts off and gets harder to crank

A bad O2 sensor would not prevent it from starting. The computer ignores the O2 sensor until the engine warms up. If the fuel pressure is good, check the engine coolant temp sensor. If that's bad, the computer may think the engine is warmer/colder than it really is and will give the wrong air/fuel mixture.

My car runs fine everythiing seems good, just had a new radiator put on it, but when my car sits running for awhile it starts to overheat, then i start to drive and it cools back down?. please help

Check the electric cooling fan. There will be a sensor on the engine to tell it to turn on. The electric motor itself may be defective, and lastly, there will be a fuse to power the motor. Also, if the engine has been running hot, it may have damaged the thermostat. But from your description, that doesn't seem likely. Hope this helps.

Why does my radiator cooling fan remain on after I turn off the ignition?

The car has a computer that is linked to the engine. It is hard wired to it meaning the computer is always on. Upon shutting your engine off taking the keys in hand the computer is still on sensing the engines temperture. The coolant sensor will send power to the relay to keep the fans running untill cooled down enough. Then the sensor will cut off power to the relay shutting off the fans

1992 Honda Accord cooling problems--Please help!

I smell a bad water pump.. If your water pump is bad you get very poor coolant circulation not to mention at a stand still(red light) you get less air flow to cool down the coolant. Since you have poor coolant circulation you wont get the proper coolant to heater core as well so you get less warm air threw heater. Not to mention that when a water pump is faulty and you have a thermostat it allows even less coolant circulation compared to a constant flow of antifreeze. I would have it checked. Good luck

P.S, I am assuming that your electric fans are working and you have to proper mixture of antifreeze and water.
