Mrcheerful

thanks mc cheerfull. its on a 2002/52 plate vauxhall astra 1.6 8v club

i get a warning on the ecu that points to the ( 1 intake air temperature sensor )

can these be cleaned or do they need to be replaced? the error code is - p0110

wiring, sensor, ecm, in that order

thanks moray :)

Should be something along the lines of a X16SZR engine code then.

It's most likely the sensor, but the only real way to know is by checking the value the ECU is seeing. Check the reading, if it doesn't seem plausible, try unplugging the sensor and see what happens. Then bridge the contacts on the connector and see what happens. If the reading changes, the sensors faulty, if nothing happens, it's a wiring fault.

You can also check one side of the wiring by checking that there is a 5v feed on one of the wires.

i only have a draper code reader, so i am unable to read the sensors/ecu in real-time. just the codes after the fact. i would love to have a setup on my laptop to read everything, but there are so many of them and they seem to do differant things.thus i have no idea what to buy for my lappy;

I think that code means your oil filler cap is on upside down.

no its one of those rare ones, like the double headed coin. :-)
