checked my classic for errors as im getting the 0.5 bar boost problem and fluctuating idle now and again and found the following :-

error code

11 - Crankshaft Position Sensor
24 - Idle Air Control Solenoid
31 - Throttle position sensor

any advice on where to go from here
regards

 

replace all 3 sensors with new ones and reset ecu

 

I would reset the ecu and see which reoccur first

Simon

 

is it ok to take out the idle air solenoid clean it then reset ecu ?

ill leave the throttle sensor as is because once u remove you have to reset the voltages dont you ?

and the crank position sensor i MAY know whats casuing it trouble theres oil all over the case wet and conjealed where this is, caused by a very slow power steering leak, could this cause it to error if its getting in ?

 

Have you reset the ecu now? if not the error codes could be very old and invalid..

reset to clear and see what reoccurs..

Simon

 

As above, they could be old codes. I remove the crank sensor every time i do an oil change, to get oil pressure before starting, so would get a fault code for it, so i reset after.Disconnecting the battery for an hour's the easy way to reset the ecu.

 

good points

ill reset ECU in morning via green n black connectors

does it take any length of time for the ecu to learn settings again or indeed flag up the errors again if they are currently real problems ?

 

if you follow the reset procedure here

the error code or no errors code will be flashed up fairly quick

it takes a while to relearn the fuelling and ignition compensations but not that you are likely to notice.

yeah good point.......forgot that one!
