Under the passenger side kick pannel, there is a pair of wires with a blue connector at the end. You might be able to find it without remove the panel, but you will most likely have to take it off (just pull it straight out). Once you find it, take a paper clip or some other piece of wire and short the connection (put one end into each hole of the connector). Put the key in the ignition and turn two clicks. The check engine light will begin to blink out the code; long blink=10, short blink=1. Just add up the numbers to get your code. Examples
2 long, 2 short = 10+10+1+1 = Error code 22
4 long, 1 short = 10+10+10+10+1 = Error code 41

If your car is running fine and your check engine light is on, you will most likely get code 41, which is the heater circuit in your O2 sensor. You will have to replace the sensor to fix it, but your car will still run okay without doing so. You can usually do this yourself with a simple socket set and renting an O2 sensor socket from your local auto parts store.

Why is my 91 honda accord ex s light flashing?


This is a trans issue, and OBD scanners won't read these. Jump the 2 pin OBD connector and count the light flashes to get the code #. Then go online to find a list of codes for your Honda.

Have a 91 honda accord. experiencing dramtic hesitation when accelerating but check engine light comes on and problem dissapears. Once you stop for a short period of time check engine light goes off and...


Sounds like your O2 sensor is malfunctioning. When the check engine light comes on, the computer goes into a preset mode bypassing the O2 sensor and that's why it suddenly runs good. Have the O2 sensor checked. You can also have the trouble codes read and they should point you in the same direction.

How do you read the trouble codes on a 91 honda


Older cars used the OBD 1 system for retrieving codes, check your owners man, for the location of the diagnostic connector under the hood, use a compatible scanner, most newer scanner's have the cable needed for making the connection. Good luck!

check your wiring for dirty connections or broken wires, you may have wires that are rubbed through or connectors that are not making full contact. you will need an ohm meter and check wires for continuity. a wiring diagram will be needed.
