I get code p0135 which is heater circuit and I know I have a bad ground. Is it possible to ground somewhere else or is it necessary to run ground all the way back to ecm.

Answer 1

P0135 Oxygen sensor heater control circuit Bank 1 Sensor 1
No you can not , the 02 sensor receives power through a fused circuit, It is the ECM that sends a ground signal to the 02 sensor , The ECM uses ground signal to control the heater circuit
