Question

I have a 97 Ford Thunder showing PO codes 135,136,141,155,and 156, what do these codes mean?

Answer 1

P0135 02 sensor heater circuit malfunction ( Bank 1 sensor 1)

P0136 02 sensor circuit malfunction( Bank 1 sensor 2)

P0141 02 sensor heater circuit malfunction ( Bank 1 sensor 2)

P0155 02 sensor heater circuit malfunction (Bank 2 sensor 1)

P0156 02 sensor circuit malfunction (Bank 2 sensor 2 )
Check and inspect the harness to the 02 sensor , and test for power at the heater circuit. Having all the vehicles 02 sensor can indicate a faulty connection rather than  faulty 02 sensor
