How to get Prelude CEL codes and what they mean

(Thanks to Schwarzpm)

Get a paperclip and bend it into a U shape.
Make sure the engine’s off and look behind the centre console near the clutch pedal for the service connector; it’s a little (normally) blue connector with 2 wires attached.
Insert the paperclip into the connector to short the 2 wires.
Now turn on the ignition but don’t start the engine, so the dash warning lights light up.
If the CEL light on the dash stays on permanently there are no CEL problems.
If it starts to flash you’ll need to make a note of how many flashes there are.
The CEL light will flash in a loop if there is more than 1 problem

Short flashes mean 1
Long flashes mean 10

This!

Much cheaper and easier than doing a 2ws conversion. As others have said, avoid fast cornering until the issue is fixed.

If it's just a sensor - PM me when you know which one, I have all four spare and fully working.

Post by **Vtecmec** » Mon Jul 30, 2012 9:23 pm

Rob, I need a rear o/s sensor, how much do you want delivered? Cheers.

Funny for sale thread, but I need rid and happy to get others 4WS all fixed up. Any corner say £20 posted?

Post by **Vtecmec** » Mon Jul 30, 2012 11:17 pm

Sounds good, PM me your paypal addy and I'll ping some cash your way for a rear O/S.

That'll be my 4WS and ABS issues crossed off my list.

Cheers

Just a heads up chaps, there are two types of sensors in use. Single bolt, and twin bolt mounting. Check which one you need/have to avoid the swearing after (been there, done that

).
