Re: Code help...
From 21 and 25 - Replace your HO2 sensor, the one between the engine and the cat converter.
43 is unrelated. Could be your ignition switch or ignition switch-starter electrical circuit. 21 is specific to the HO2 sensor. 25 is more general and could refer to many thing. See if it goes away when you replace the HO2 sensor and reset the ECM. Make sure the HO2 sensor connections are clean
