Hi .

Thank you for using justanswer / pearl for your automotive problems .
My name is Greg and i will do my best to assist you with this code problem .

The code P0428 Catalyst Temperature Sensor High Input Bank 1 Sensor 1.

Possible causes:

Faulty Catalyst Temperature Sensor.
Catalyst Temperature Sensor harness is open or shorted.
Catalyst Temperature Sensor circuit poor electrical connection.

This problem normally means the cat is damaged and needs replacing ,the sensor is detecting a over hot cat due to being damaged . or the sensors has failed and needs replacing .

Have the sensor checked with the scan tool to make sure it is working if good replace the cat .

If the sensor shows bad replace the sensor .
