We replaced the #1 eng oil temp sensor a while ago as it was reading 20-30degrees C hotter than the #2 engine even at ambient temperature. After that the aircraft operated normally for 2-3 weeks and then started showing up with this oil px warning problem. Could it be the coil in the N1 sensor supplying the ECU is giving an incorrect signal?
As for the position, if you have Arriel, LTS101 and Allison would be happy to talk
