P0141 CHEVROLET -

Question

I keep getting same code after I replaces both sensors all fuses are good could a thermostat make this code come up by not letting my car warm up enough

Answer 1

P0141  02 heater sensor circuit malfunction.Bank 1 sensor 2.

No a thermostat will not set P0141. This is a heater circuit code. you should have B+ on the heater circuit wire.Go to the bank 1,where is bank 1 that is where number 1 cylinder is located, the 02 before the catalytic is sensor 1,so after the catalytic is sensor 2,a improper connection of this 02 sensor will set off P0141,so would a faulty 02 sensor, remeber you need B+ with engine off key on
