P0420 repleced sensor 2, then got P0037 O2 Sensor Heater Circuit Low Bank 1 Sensor 2
Hi all
I got p0420 bank 1, I replaced the exhaust sensor , the first code gone but I got another code which was P0037 O2 Sensor Heater Circuit Low Bank 1 Sensor 2, The mechanic told me we need to replace the front Sensor which sensor 1 as well ? is that logical ?
Thanks all
