deadpool2e Posted February 5, 2006 Author Report Posted February 5, 2006 please help its freezing in the car......:blink: Quote
dave_m Posted February 5, 2006 Report Posted February 5, 2006 Aux heater is controlled by its own temp sensor, The air intake sensor measures the temperature of the inducted air flowing into the engine, still would get this replaced though if it is faulty as i think it will be affecting the way your engine runs and will be using default values and your engine won't be running at the optimum efficiency see the aux heater post for more advice on why your aux heater is not working! :) Quote

(some where after MAF???) Quote
seatkid Posted February 5, 2006 Report Posted February 5, 2006 It a small cylindrical can stat located in front of the pollen filter. Just short it out (a car fuse fits fine apparently) and your heater should fire up when the coolant temp is low (thats a different sensor built into the heater unit) Quote
dave_m Posted February 5, 2006 Report Posted February 5, 2006 see below for air intake temp and pressure sensor, This is what the fault code will relate to (nothing to do with aux heater) I got this info from Elsawin. It was the only component called intake temp sensor so i think this is the one you are after. Quote
dave_m Posted February 5, 2006 Report Posted February 5, 2006 The one that switches on the aux heater at below 5 degrees is located behind the scuttle panel under one of the wiper linkages see image below. as seatkid says you can bridge this with a fuse to test it out. hope this helps Quote
Masked Marauder Posted February 5, 2006 Report Posted February 5, 2006 http://www.bigtrucker.co.uk/images/heaterswitch.jpg This is the switch. You can just make out the connector with a 10A mini-fuse plugged into it in the right of the picture. Quote
Steven.Langdale Posted February 5, 2006 Report Posted February 5, 2006 MM That Pollen filter is looking a bit past it's best! You know you want to change it! :) Steven Quote
Masked Marauder Posted February 6, 2006 Report Posted February 6, 2006 When the picture was taken the pollen filter was about eight weeks old.... Quote
deadpool2e Posted February 6, 2006 Author Report Posted February 6, 2006 thanks for all the info, will attempt it all at the week end and let you know how i get on. and double thanks for the guys that supplied diagrams and pics....thumbs up Quote
deadpool2e Posted February 14, 2006 Author Report Posted February 14, 2006 replaced glow plug in 2 1/2 hours with help from other threads in this forum and the aux heater now works (got glow plug from a guy on ebay for Quote
