The English version of P0135 is Oxygen Sensor Heater Circuit Malfunction (Bank 1, Sensor 1). That's the only one showing after disconnecting the battery for about 10 minutes and then driving it about 15 minutes. I've contacted the guy that did the swap to find out if he did something the fool the DME so that it wouldn't show the air pump code. If he didn't I'm completely mystified as to why it's not showing me a real air pump code. I would expect to see one of the codes below, but I've got nothing. Thanks for the help so far and if anybody can think of anything else to try I'd love to hear it. I'll definitely keep the thread updated with whatever I find out.
