My first calibra engine codes problem :(
hi all,
had me first encounter of calli trouble today [img]/sad.gif[/img]
On M25 doin 75-80mph when i felt a sudden judder and lost alot of power and my engine management light came on (imagine this must have been limp mode)
Tested the codes in the ECU and got these... please help me out!
23 - Knock Sensor - out of range
12 - haven't got a clue for it!! 13 was oxygen sensor (open circuit), maybe that one?
15 - Coolant temperature - voltage high
when i started it back up, the engine light remains, but it didn't seem to be in 'limp mode'
give me some clues! please! :confused:

The 12 is just marking the start of the code readout, its always 12,12,12 then the codes then back to 12
the coolant tem sensor is the one on the thermostat at the front of the engine, theres two of them but its the one with the larger plug, nearest the air filter that the ecu needs, the other single wire one is only for the gauges on the dash
the knock sensor is on the back of the block and is a pain to change , but often its the plug or wire especialy if its intermittant and i suppose that if the water temp was giving a wrong reading it might effect the value that the knock sensor thinks it should get (but im not sure on that)
If you need to reset your ecu dissconect the battery for 5min , then there should be no codes and you will loose the limp home mode.
the limp home mode usualy restricts your engine revs when its there until you reset the ecu

cts is only about £8 so not to bad.... see what comes up after the code wipe... check the connections and make sure they are clean too<!--QuoteEnd--></div><!--QuoteEEnd-->
nice one mate, never knew all that stuff went into engine design, to stop the thing destroying itself!
bang on! [img]/smile.gif[/img]

checked out the coolent temp sensor (believe it is, blue plug) and one of the connections has broken off! So i guess thats a repair job
regarding the battery, there is this blueish white powder round the bottom of positive battery terminal... whats that? am i going to die touching it?!
Definately feel i'm getting somewhere though! thanks for all your help Rog [img]/smile.gif[/img]

I havent seen that white powder on the battery, since i had a old cortina...till the other day on one of my lorrys that wouldnt start, its usualy there when your battery is stuffed!, mine were 2 of them at 65 pound each!
i think its the battery acid that has dried but since its on the lead i supose its lead sulphate as well from the reaction between the lead and the sulphuric acid
I wouldnt get it in your eyes...., but i have in the past and its never done any harm, it might put holes in your clothes though its not realy toxic or anything like that but i wouldnt eat it!
If the battery seems ok, clean it off and put vaseline all over the terminals and battery contacts will stay better and you dont get the powdery deposits.
