It's not really a switch. Below is a desciption of what the code means. In about 50 percent of the cases it's a bad connection which is causing the failure and there are many tests to check different circuits. In order to rule out the ignitor here is a quick test you can do. Below is a picture of a breakdown of you distributor (yes the ignitor is in the distributor). Take the distributor cap off. Using a digtal volt meter check with your postive probe the black wire terminal connected to the ignition coil and ground the negative probe to a good grouns like the battery. Make sure you are getting at least 10 to 12 volts. If you are check the connection at the brown and black wire between the coil and the ignitor and make sure all is good (like good continuity) If all is good, chances are the ignitor is faulty. If you are not getting the voltage on the first test right at the black wire terminal at the coil the coil could be faulty. As I said it's a 50/50 thing on this code as far as wiring or a componant such as the coil or ignittor. I have found in the past that in most cases if say a coil or ignitor goes bad, it's just bad and you end up in a no start situation but there are those odd cases that outside temps effect everything like engine heat or a componant over heating.Hope this helps and good luck.
I will enclose a wiring diagram to help you in checking the wiring.
Code 14 is ignition signal circuit , No ignition signal.Here are a few things to check.1} check for 5 volts signal from the ecm.2}verifies 0.10- 2.0 volt signal from (ecm) engine control module)3}check for power to distributor.4}check for open in black/orange wire between junction block no.1 and distributor or for a faulty junction block no.15}check for opens in power wire to Igniter. or a faulty ignition coil or Igniter6}check for open in red/black or black/orange wires to ignition switch and a faulty ignition switch
This problem may be a bad wire or bad ignition switch. the igniter may be bad but not to often do i see an igniter go bad.Most of the time its due to a bad ignition switch due to internal problem or bad wire connection at ignition switch. also check the wiring to distributor and to igniter.
The wiring diagram will help. hope this is helpful. good day.
SOURCE: Does anyone know what the code 21 means on the
The code would be your o2 sensor which probably should be replaced:)
SOURCE: took my 1994 Geo Prizm to a car part store and
what was not done they code was not clear properly take it back let them do it over
SOURCE: engine code 14 ignition signal and code 26 rich
I would start by replacing the primary ignition system,cap,rotors,wires,you can't just check these items they could be defective where you are unable to see.a rich condition can be caused by a mis fire from a wire,a bad tps,or 02 sensor,but I would always start with the basics and not overlook them,if you need any more help let me know.
