2000 amigo v6 automatic rwd PO 134+154 at same time

Postby teslaactual » Mon Feb 15, 2021 4:55 pm

I've replaced all 4 of my O2 sensors because one was dying and after I replaced them I've been getting my check engine light and both PO 134 and 154 at the same time, when I took it to the shop the guy said that his scan was inconclusive and when I went to a second opinion at a different shop he said that the PCM drivers for the O2 sensors had been corrupted, the only other symptoms is a bit of a rough idle and stalling out randomly when I go from park to drive or when near idling, the guy who said it was my PCM didnt seem too confident and wouldn't really go into a lot of detail, is there any other thing It could be before I go and get a 1200$ PCM/ECU

Were these plug and play O2 sensor replacements or did you have to cut the wiring and splice in universal fit replacements.
What brand and model sensor did you use.
Imho not likely you have a defective PCM, check the wiring.

They were plug and play the brand was Zenithike,I'll see what I can do about checking the connection, the passenger side upstream is a pain because its halfway up the engine bay in a tiny little cranny
