Baromatic pressure sensor,

[DTI Dave]

located next to the airbox, does this sensor have some sort of pipe that plugs in underneeth..... my car is throwing a code with this sensor fault, but there is nothing plugged into the bottom of it nor can i find a pipe that may connect to it/

any ideas?

Hi dave
no there is no pipe , what often happens with these sensors is the electric contacts become oxidised and cause them to go faulty try cleaning the contacts and blow any dirt out of the pipe then replace it sometimes this is all it needs otherwise its a new one pt no 2442 6679 about £55 from the stealers

yea i got another off an 04 plate. £20 so hopefuly this sorts it out..

does this sensor affect performance or mpg etc?

When mine went faulty it was showing 1.6 volts across the sensor (on Op-com) instead of 4 Volts, but the sensor was still showing the correct barometric pressure.
Not sure what was happening, but I changed it anyway.
I'm not sure what difference it made as I also had a faulty turbo at the time too.
But I think that the ECU needs to know the atmosphere pressure to know if the boost pressure is correct.
