Chances are your knock sensor's not shot,as if it picks up a high knock level,will give you a code. If the maf has gone,could cause this.

WELL PEOPLE I HAVE FOUND THE SITE THAT SHOWS ME THE CODES BUT ITS TOO CONFUSING!!! BASICALLY HERE IT GOES ...WHEN I PUT THE IGNITON ON WITH THE WIRES CONNECTED

I GET

2 LONG PULSES 2 SHORT PULSES AT ONCE THEN A LITTLE GAP THEN

2 LONG PULSES 3 SHORT PULSES AT ONCE THEN A LITTLE GAP

2 LONG PULSES AND 4 SHORT PULSES AT ONCE THEN IT GOES BACK TO THE START AND KEEPS GOING IN THIS SEQUENCE SO JUS SAY ( 'L' REPRESENTS LONG PULSES AND 'I' REPRESENTS SHORT 1'S IT WOULD GO LIKE THIS).

L,L,I,I

L.L.I.I.I

L,L,I,I,I,I

AND KEEP REPEATING THAT SEQUENCE ANY IDEAS!?!?!?!?!?!?!

rob73

thats 3 faults that has been stored. you have a code 22,23 & a code 24 there bud. the long pulses represent the unit of 10 so 1 pulse would be a 10, 2 pulses would represent 20 & so on. The short pulses represent single unit like 1 pulse =1,2 pulses=2,3 pulses=3 & so on. Simple really bud.

millitant_sti

so do i add these up and then i will know what is wrong???

Check this JollyGreenMonster.co.uk

Courtesy of the JollyGreenMonster. I find all the info here, from Simon, is very helpful.

millitant_sti

ah thanks mate some other guy told me to add them up and that would be the problem (only1b0 ut that obviously aint the case. so basically i have three problems are these all major 1 is my knock sensor, 1 is maf, and the other is Idle air control solenoid are these common parts to go on a scooby

millitant_sti

ive sourced all the parts for it so should i just change them all at once?

do your codes come up straight away mate soon as you start the engine? cheers

rob73

yes change them bud then do an ecu reset,then run the car for a while then do another fault check just to see alls ok

millitant_sti

they come up once ive connected the black wires and put the igniton on!

just a simple batter removal will do a ecu reset true???? and also ive found maf and knock sensor but the idle air control solonoid is a bugger, would i get away with just fixing the 2 while i look for the air solonoid, also what is the cause of these failures??? i know the maf probobly went due to my apexi air filter and could the knock sensor of gone due to using normal unleaded sometimes??? and why would the solonoid go???

Look at the top of the page,not sure what it's doing up there!!!

This may help from a guide i posted on P1WOC:

If your CEL is constantly illuminated (CEL – Check Engine Light), you can do a do a CEL check to obtain the fault code.

To do this, you need to locate the 2 green ‘test mode’ connectors under the steering column:



Once these are connected, turn the ignition on. You should now here lots of clicking and fans spinning from the engine bay.

Take a look at the CEL and you should notice that the CEL will flash in a sequence. This related to the fault code.

This is how you work it out...



A long flash equals 10, and a short flash equals 1. Total them up to get your error code. You should also be aware that if more than 1 error code is present, the CEL pulse sequence will change. The change in sequence is easy to identify.

You are also able to read previous fault codes that the ECU has stored. This is helpful if you you’re CEL flashed up and is not constantly illuminated and if you just want to be inquisitive.

To do this, you need to locate the 2 black ‘read memory’ connectors (pictured above) under the steering column. Join the connectors together and switch the ignition on, then use the ‘pulse’ method as above to obtain the fault codes the ECU has stored.

As with the CEL pulse in test mode, more than 1 error code may be present, causing the CEL pulse sequence to change. The change in sequence is easy to identify.

sorry to hijack the thread but mines not coming up with anycodes straight anyway but after a couple of miles driving as i was reseting the ecu it seems to come up with a code is this a previous code as the ecu has been upgraded & was from someone elses car?

-Spooky-

are you connecting the black or green connectors?

w13dle

iTrader: (5)

i connected both when i did it black & the green

-Spooky-

just connect the green 'test mode' connectors.

the black are read memory connectors...
