My 2004 honda accord lx 4 cylinder, 4door, won't start, i checked if the spark plugs where getting a spark and they were not, where can i find the sensor that sends the spark to the spark plugs.

SOURCE: having trouble locating the Air

It's located on the air filter housing. Two
screws and a connector.

SOURCE: finding where the speed control

There are actuly 3 of them . It depends on what code your getting . There is ine on each front wheel some times they have connection problems because of the connecter locations water road salt things like that but these will give you a code and the vehicle will still run alright in most causes . The third one is on the tailstock of the transmission near where the drive shaft comes . This is the most important one . There all little generators so voltage dose not go to them they send a referance voltage to the vehicle control module. If the vehiche is not running properly look at the one at the back of the transmission but check the whole system . You can test the ones on the front wheels by unpluging the connector and spining the wheel with a volt meter hooked to the connector you should get around 5 volts DC or so if you do then there OK and you need to look at the main one that sends the signial to the VCM on the tailstock of thr trany. Hope this is not confuseing just remerber there are all little generators and put out voltage Good luck john
