S40: - ECU codes and alarm fault

Mark taylor · Jan 26th, 2014, 13:48

Hi all. New here

. I have a S40 !.8 petrol, X 2000 year. I Have an ECU code of PO133. I have a split Pre heater hose, could this be the problem?

Also have an issue with my alarm. I have the sensors inside but dosnt activate them. The deadlocks work as does the immobilizer. Just wondered if there was a way of activating it?

Thanks

Mark

Don't know about your engine codes, have a look here http://www.volvoforums.org.uk/showthread.php?t=79531

For your alarm - do the indicators flash once when you arm it?

no they dont, but they flash twice when disarming it

Very likely that the bonnet tamper switch is not making contact - you can find it between the bonnet catch and the radiator. Put your finger on the metal leg and you'll hear/feel the switch click, then arm the alarm and see if the indicators flash. If so, you need to re-align the switch - pics here http://www.volvoforums.org.uk/showthread.php?t=43013
