No. 1 CYLINDER POSITION (CYL SENSOR)

Try another known good distributor. The signal comes from inside the distributor.

Check engine light on


1990-95 FOUR CYLINDER ACCORD AND 1992-95 PRELUDE
See Figures 7, 8, 9, 10, 11 and 12
On 1990-95 Accord (except V-6) and 1992-95 Prelude, the codes are read from the check engine light after the two-wire service connector has been jumpered. On Accords, the service connector is under the dash on the passenger side. On Preludes, it is located behind the center console. 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).

  1. Use a jumper wire to connect the two terminals of the service connector together.
  2. Turn the ignition switch ON ; the check engine light will display any stored codes by rhythmic flashing.

In the event that a code is encountered which is not on the chart, re-count the number of flashes. If the code is truly wrong, it will be necessary to swap the ECU for a known-good unit and recheck. Since this can be expensive, you may wish to bring the car to a reputable repair facility if no other cause of the failure can be found. This may save you the expense of purchasing an unnecessary part.
  1. If no codes are displayed but a driveablity problem exits, testing of the system individual components is necessary to find the problem. If codes are displayed, follow the appropriate troubleshooting chart in this section.

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.

TROUBLE CODES System Diagnosis READING CODES When the "Check Engine'' warning light on the dashboard comes on and stays on, it indicates a problem in the fuel injection/emissions system. Check the ECU for fault codes. On certain models, some codes will not trigger the check engine light; if driveability has suffered, check for stored fault codes. The most common error when using fault codes is to assume the indicated component has failed rather than checking the entire circuit. The presence of a trouble code means simply that the electrical circuit for the named component is not functioning properly. For example, a code for the oxygen sensor circuit does not automatically mean the oxygen sensor has failed. A wire terminal may simply be loose or corroded at the connector. When using diagnostic or fault codes, always remember that the entire circuit including the component must be checked carefully. On 1990-95 Accord (except V-6) and 1992-95 Prelude, the codes are read from the check engine light after the two-wire service connector has been jumpered. On Accords, the service connector is under the dash on the passenger side. On Preludes, it is located behind the center console.

1991 honda accord idles funny and feels like its running hard at about 60 mph check engine light also comes on once i hit that speed


Remove the pass side kick panel (Plastic Part) that would be near the right of the passenger's foot. Locate a small blue plug. You jump the terminals together inside the plug with a paper clip. THEN, turn your key ignition on to power up everything but don't engage the starter. Count the amount of times the check engine light flashes. It's like morse code. A solid longer blink indicates the amount of the first number... a quicker flash will indicate the second number. Here's an example: ___ _ _ _ _ That would be code 14. Let me know what code you get and write back... I don't have room to list every code for 90-91 Accord. I'll check back frequently.

89 Honda Prelude failing emissions rich


is everything stock? and you have catalitic converter in place?

Stop by Schucks auto supply and have them run the codes. i'm sure there is a code if you cant pass emissions. your check engine light bulb is probably out.

and usually the first cause is the first o2 sensor.

How do I get a code from computer in 91 honda prelude


UNDER THE GLOVEBOX INSIDE THE PASSENGER KICKPLATE NEAR THE FLOOR IS A TWO WIRE CONNECTOR BEHIND THE PANEL. JUMP THIS CONNECTOR WITH A PAPER-CLIP AND TURN THE IGNITION SWITCH ON AND WATCH THE CHECK ENGINE LIGHT TO COUNT THE FLASHES. ONE LONG FLASH AND THREE SHORT ONES INDICATES A CODE OF 13. IF THERE IS MORE THAN ONE CODE THEN IT WILL FOLLOW THE FIRST CODE. THIS WILL SOLVE YOUR TROUBLES I AM SURE. LET ME KNOW. GOOD LUCK. P.S. IF YOU WANT TO ERASE THE CODE(S) THEN DISCONNECT THE NEGATIVE BATTERY TERMINAL FOR 10 SECONDS. BUT YOU'LL HAVE TO RESET THE CLOCK AND PRESETS.

Engine light is still on after we have replaced numerous parts


The engine light is on, Have u checked for fault codes? To check codes, pull back carpet on passenger side of car to expose ECU (electronic control unit) at 'foot' location on that side. There is a small LED display at the top of the unit, turn the key on (not running) and check for flashes, u must count the flashes to determine what codes are stored in the computer. Short flashes are for codes 1-9, two digit codes use long flashes for the 1st #, followed by short for the 2nd. There is a pause between codes, so there may be more than one. Check and let me know what u find.

Check engine light is and my s1 light is on in the drive


If your check engine light is on then it means that there are codes stored in the computer. The easiest way to find out what they are is to go to an Advance Auto Parts Store or Autozone as I know they will read the codes and tell you what they are for free. If you do not have one of those stores around you I would suggest finding any auto parts store that offers a free diagnostic check. Once you know the code then you will be able to fix the problem. I am not sure why the S1 light is coming on but I do know that the first step to fixing your problem will be to get the codes read. otherwise you will just keep guessing. Hope this helps.
