Hurtenstein Posted April 18 Report Share Posted April 18 My WRX6X has AN Temp 4 stuck on 5V. There is some confusion in the drawings as the quick start says Temp 3 is pin B136-19, but also says T3 is on the expansion loom. Ive used the expansion T3 for oil temp and get a change in readings when i plug/unplug so i'm presuming that the onboard Temp is actally Temp 4. B136-19 has no wire in the plug from factory, so i added one in. Even with my new wiring connected or not, I still get 5V on Temp 4. Any ideas?

Adamw Posted April 18 Report Share Posted April 18 There is no temp 4 on that ecu. The manual is correct, temp 3 is available on both the header and expansion. Quote Link to comment Share on other sites More sharing options...
Hurtenstein Posted April 18 Author Report Share Posted April 18 Spew. I thought there was 4 like my Xtreme and the manual had to be typo. It's all wired up and terminated. I planned to just figure out which was the double up once it was wired and I could see the values. Can I use a spare AN for IAT with a wired in pull-up resistor? Or does the ECU only look for IAT on the Temps? B136-1 (2 slots up) is a spare AN for me and I can just shift the pin. Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 18 Report Share Posted April 18 Yes you can use a Volt input with external pull-up. 1K to 5V would be my suggestion. Quote Link to comment Share on other sites More sharing options...
