Check Engine Light Help
I am new to the board and desperatley need help. I am driving my father's 1992 Honda Acoord and the check engine light is coming on occasionally. I talked with a mechanic and he siad you need to use a jumper to read the codes. I have seen several of you say Auto Zone will read the codes for free. WIll they do it in this situation? If not can anyone give me instructions or reference a link on how to do this myself I would greatly appreciate it. I tried searching but couldn't find anything. Thanks in advance.

RE: Check Engine Light Help
down in the passenger side foot well, there is a kick panel right where the bottom edge of the door opening starts to go up, it is right below the glove box. its just a piece of plastic. pull it out. underneath that is a blue connector with two wires that is not connected to anything take a paper clip or wire or whatever and jump the two prongs. now turn the ignition to the on setting and the check engine light is going to flash, this is how you read the series of flashes
codes 1 through 9 are indicated by a series of short flashes; two digit codes use a long flash for the first digit followed by the appropriate number of short flashes. For example, code 14 would be indicated by 1 long flash followed by 4 short flashes. Codes are separated by a pause between displays. Multiple codes are transmitted in an alternating pattern. For example, a code 3 and 14 would be displayed as 3 short flashes (for code 3) followed by the separator pause, then 1 long flash and 4 short flashes (for code 14).
code0 = ECU
code1 = oxygen content
code3/5 = manifold absolute pressure
code4 = crank angle
code6 = coolant temperature
code7 = throttle angle
code8 = Top Dead Center position
code9 = no1 cylinder position
code10 = intake air temperature
code12 = exhaust gas recirculation system
code13 = atmospheric pressure
code14 = electronic air control
code15 = ignition output signal
code16 = fuel injector
code17 = vehicle speed sensor
code20 = electric load detector
code30 = A/T Fl signal A
code31 = A/T Fl signal B
code41 = oxygen sensor heater
code43 = fuel supply system
i believe this is what you wanted to know

RE: Check Engine Light Help
usually if you take your car to get it diognosed and they figure out what's exactly wrong with your car and you decide to fix it there; a good mechanic would convert the charge for the diognose towards the repairs. just ask around.
or you can do what lightshow advised.
also you can buy an obd reader. just the reader only that gives out codes will cost around 120 bucks (for a decent one).
