1995 Honda Accord Blinking light and no Speedometer

  • 4 CYL
  • FWD
  • 164,680 MILES
On my instrument panel, between my speedometer and tach is a representation of the shifter gears. Current gear is shown by a light (gear-light). As I was driving down the road the gear-light began blinking and my speedo needle was jumping like a kid on a trampoline. I turned all accessories off and continued driving listening for any changes. There were no noises. My car has been sitting for 2 years and I just started driving it again. Prior to it being parked I had been noticing that my mileage was dropping. When I got home I performed a self-test on the car and although the check engine light did not blink the gear-light did again, in groups of 4. So cross referencing with Hanes, I checked the CKP sensor (Crank Position Sensor), determined it to be bad and replaced the distributer 9-24-09. While driving yesterday, 9-25-09, I had the problem occur again. While the light is blinking and speedometer is jumping there is no performance change. Also when I shift into other gears my gear-light still indicates which gear I do into, with the D4 light blinking. It doesn’t do it every time I drive and so far will either fix itself on its own, or work properly if I turn car off for a minute ad then restart.
Do you
have the same problem?

Hi Black Jester,

Engine and transmission codes are different. When the D4 light is blinking, the trans ECM has detected a fault and a code 4 means trhe speed sensor or its ciruit is faulty. If it does shouw with the Check engine light blinking when retrieving codes, it should show as 17 blinks. You have mistaken the trans trouble code for the engine trouble codes.

You would need to replace the Vehicle Speed Sensor to get the speedometer working correctly again and get rid of the blinking D4 light.

When the speedometer is not working correctly, fuel consumption and shifting points would be affected.
