  1. BALIKBAYAN Really appreciate them files that will really help me I have cleaned out maff sensor properly this time as the maff and IAT sensor are on the one unit and thinking I was cleaning maff I was actually cleaning IAT Hotwire which is the wire on outside when the wire for maff sensor is hidden up in the plastic a couple off blasts of carb cleaner and blowing it out with air seems to have sorted it out engine light has gone out and no more limp mode car runs and sounds a lot better thanks again pal for the files it is handy to check the specs and voltage back probing them wires as they do corrode over time
  2. I think the it’s 2 sensors in one unit the maf and I a t sensor
  3. It is the d4d 2litres t 25 avensis 6 speed manual timing chain engine 2008 model
  4. Lads engine light back on again I have no access to scanner but took readings from backprobing map sensor connecter can anyone make sense off these readings I havent got manual backprobe readings with engine running 01- 0 volts brown wire I think it’s ground wire to sensor 02- 2.7 volts green and red wire I think it’s 5 volt ref Wire 03- 1.5 volts green wire I think it’s signal wire back to ecm 04- 0 volts blue and yellow wire I think it’s bat ground wire 05- 14.1 volts black and white wire I think it’s bat positive wire my question is would my sensor be bad I’m not 100 percent sure but I think my wiring seems good any help would be appreciated
  5. Lads just a quick reply done this job Saturday took out the throttle body under inlet manifold where egr sits very inconvenient to get out but it’s gets dirty cleaned it out put back in cars seems to be alright for now engine light has gone out
  6. Cheers for the reply I will tackle this tomorrow it seems to be quiet common in avensis d4d it think the throttle body sits directly underneath egr valve on intake so hopefully this great piece of knowledge will help me diagnose and fix the problem I will keep you updated on this cheers for the reply
  7. Lads I know where throttle body is on petrol it’s under air box but on d4d avensis don’t know location is it under egr valve or does it run between air hose going in to turbo getting p0488 code
  8. Lads does anyone know if there is a standard fit non ac serpentine belt to bypass ac compresser or do you have to measure the pulleys with string
  9. I did mine Christmas just gone when removing drive shaft remove the 2 bolts spray wd 40 on them to ease removal when bolts are removed come behind drive shaft and tap drive shaft gently out off housing with a punch and hammer to remove it as far as I can remember remove serpentine belt with tension draw on paper correct routing of belt on pulleys for reasembling remove electrical conecters there’s is I think as far as I can remember 2 or 3 bolts holding alternator on when bolts stubs are removed the alternator will come out the space where drive shaft was there is a video on YouTube off it when reassembling the alternator put a multimeter set do dc volts on battery + and - readings should be 14.2 volts to 14.6 volts then test the battery on load put lights ac and radio on it should drop to 13.8 for a healthy alternator best of luck
  10. Yes I was thinking this aswell the 2008 t25 transponder chip seems to be hard to get
  11. Hi lads bought a replacement key off amazon looks exactly the same as master key with remote and transponder chip when I go to program both the transponder and remote it fails to program I am using techstream version 13 when it’s on the register screen it counts down to from 70 secs gets down to 10 secs then says operation fails ecu fail to communicate with key

    Ac radiater fan

    Lads when I disconnect the coolant temp sensor fans kick in on high speed so the fans work The slow speed fans don’t come on when ac button is pressed it could be low refrigerant in cooling system The high speed fans don’t kick in when car reaches the halfway mark like they used to question is is the coolant temp sensor the fan activation sensor as well does it do 2 jobs activate the fan and control temp gauge in car as well I have checked all fuses blade fuses they are okay I can’t get cube fuses to come out to check them plus the denso relays when checking them they have 4 pins no diagram on it do you connect power to small pins then check continuity between larger pins plus I think it’s a 19 m deep socket for coolant sensor any help would be appreciated thanks lads
  13. Lads I was bleeding the clutch left a mini torch in between radiater for more light and forgot about it drove around for a few hours before realizing what I had done when I took it out there seems to be no damage done but before when I pressed ac button inside car one of the fans would run no this fan has stopped running plus when when car heats up as before the 2 fans would kick in no they don’t I don’t know if I damaged something
