C20let fault code 71 (ATS)
« on: June 24, 2018, 22:59:43 PM »
Hi all,

My astra F with Let setup is throwing out error 71. Tested the voltage on the sensor and I am getting earth but no voltage into the plug.

Any suggestions?

Trace the cable back to the ECU and make sure you have a voltage there. If you do then you’ve got a break in the loom (or something quite common with age). If you don’t then your ECU has some form of fault - which I’d recommend you get repaired rather than try and swap.
