Help me P Adams or other
90 Accord LX >300Kkm Check Engine light ON. Changed O2 sensor. Light still on. Also Speedometer and odometer not working. Not sure when it stopped but definitely not longer than a week .Not a mechanic had a friend help me. Can we fix it or what ?

 

90% chance its the speed sensor.. Is your D4 light flashing too?

 

What is a D4 & the Speed Sensor ? Where are these located?

 

Did you bother to have the CEL light checked?

 

Thanks 1grex Sure U R right but don't know where to locate the speed sensor I'm not sure where the speed sensor

 

Muffinman is right too, very easy to verify what the light means; pull passenger side kick panel and jumper the open connector with a paper clip with key in position 2, and read the flashing CEL.. The speed sensor is bolted to the transmission. Use Autozone's Z-Net component locator..If a list of trouble codes isn't on Z-Net, then go to the store and look in a Haynes manual, you don't have to buy it.

 

The VSS (Vehicle Speed Sensor) is mounted to the transmission case above the differential housing - it measures the rotational speed of the differential thus indicating vehicle road speed.
It can:
Set off a flashing D4 indicator
Set off a CEL (check Engine Light) (and subsiquent DTC code)
Keep the speedo from operating.

I'll see if I can scare up a pic or two.

Here's what it looks like:

I don't mean to come off as rude but it *could* be unrelated - while the flashing D4 you indicated in the post right after me means it's the VSS there's no reason to spend $$ on a VSS when that isn't the problem.

I'd have the CEL checked THEN start replacing what it says is wrong.

The cluster issue could be a problem with the cluster itself - rather than the VSS (which was my case along with many others)

 

Thank You 1grex, Muffinman and P Adams My friend ( backyard mechanic) and I will work on it and I'm sure we'll get it sorted Thanks

 

if the tranmission fluid is low will that cause the d4 light to blink becuase my 1992 honda accord lx has been sitting for more than 6months
