CATLESS MIDS.... THROWING CODE

[FaSt ReD SrT10]

Hey guys... just got done with the install.... VERY LOUD... but sounds sick...

Throwing this code.... P0031-O2 SENSOR 1/1 HEATER CIRCUIT LOW - SRT10

Which sensor is this? I know it is an upstream... but which one?

Did u install a pair of oxgen simulators "O2 sims" in place of the factory sensors near the mid-pipes?
These simulators, available from supporting vendor(s), will prevent a certain code - probably the one you are seeing - from being thrown.

Sims are in his sig line, so I presume he does.

As I recall, that should be the driver's primary (upstream) sensor throwing the code.

It's a PITA to get at that connector, but after a mid-pipe install, it may not be getting a good connection at the harness coupling.

Ok - then assuming they are installed and not just in the sig line pending install, the wires could possibly swapped on one or both of the sims.

The sensor that is throwing the code is, again, an upstream sensor, so he'd be seeing a DTC on sensor 1/2 or 2/2 The downstream O2 sensors are the ones that get the SIMs.

Unless you mean that he swapped the upstream and downstream sensor leads, which is physically impossible of course.

Anyway, P0031 is for Bank 1, Sensor 1. (upstream driver's side sensor)

The sensor may have become fouled in the installation process, or the engine was run with it disconnected (bad for O2 sensors).

Here's a handy Dodge OBDII reference for anyone that wants it:

Okay maybe I stretched the truth a bit..:dontknow:

Thanks for your help guys... the connector on the Harness wasn't plugged in all the way... I reset the computer... AND NO CODES!!!!

The Truck sounds absolutely insane right now... and I am going to get Pics and good videos today

Yeah.. I recall that issue now on mine.. did not throw a code.. but I had a hell of a time getting to one of the connectors on the front O2s, but was eventually able to get it plugged in... it sat almost nearly dead center on the top of the tranny...
