hi out there

Car arrived with p0053 o2 sensor signal, p0130 upstream sensor open circuit, p2178 mixture regulation, p2196 upstream signal coherence

Sure enough scoped & no activity,changed sensor & carried out adaptions using dec3
3 days came back with one code p0053, which relates to the heating circuit & sets after a few start ups
aftermarket sensor used!!!
would like to share wave forms with you, on the second one which is from cold there is a period of extended heating activity?, is that normal, may be nothing? however 02 is inactive & open loop for about 8 mins,is that to long?
please ignore channel 3 at the start, the wire came out.

please see the next post
