Please Help installed brand new sensor
 Error message POO31 and  engine light back on  P0031 Toyota MR2 SPYDER-

Answer 1

P0031 Oxygen heater control circuit low (Bank 1 Sensor 1)

This code is circuit high what can set this is if there is a poor connection to your 02 sensor.

 Here a brand new 02 sensor set a P0031, the problem the 02 sensor was not properly torque down.
