5.7 Hemi 2500. Where can I get a wiring diagram for the O2 sensor?

The camshaft position sensor on a 2012 Ram 2500 with a 5.7L Hemi engine is located on the front of the engine, near the timing cover. The sensor is responsible for detecting the position of the camshaft and relaying this information to the engine control module (ECM).
To access the wiring diagram for the camshaft position sensor, you will need to consult the service manual for your vehicle. The wiring diagram will provide you with the location and function of each wire in the camshaft position sensor circuit.
The service manual for your vehicle can usually be purchased from the manufacturer or from a third-party provider. You may also be able to access the service manual online, although this will typically require a subscription or fee.

OXY SENSOR IS SHORTED(was)AF (named by Lexus oddly)
THE FUSE BLOWS IF SHORTED DID IT? 25amps blew up?
AND WHICH RELAY, EXACTLY.
both p1135/55 means , B1S1 and B2S1 both front sensor heaters are dead but gee wiz with relay pulled sure they are. dead.
AF heater relay runs both those 2 front O2 sensors
and if either of the 2 short. fuse marked AF heater fuse blows 25AMPS
The heaters are spec at 5 ohms so each heater uses 3amps 6 total paired, and 25amp fuse does not blow.
but if the 2 heaters B1S1 and B2S1, short the fuse blows.
so bad 02 front sensor. or wires to them melted or cut in half
wires on O2 , with clamps missing allow wires to touch 2000f header pipes(exhaust ) and melt and burn up, and then short.
or even burn open.

or put in the wrong 2 front 02 sensors or used the cheap ones
$20 that are hand wired, and wired up wrong.. (done lots but not wrong yet, I'm careful) I run BOSCH only, and or OEM fit
and easy to pop in, the Bosch web site has the Ecatalog to get the correct ones. from them.

The O2 sensor is in your exhaust pipe leading away from the exhaust manifold connection. It will be the only sensor in the pipe itself. Look on BBB Industries online for a wiring diagram if you need one.

Perhaps if you had bothered to tell us year, make, model we could have looked at the wiring diagrams to see if there's a common circuit.

Should be in the exhaust pipe just after the catalytic converter.

The pink and black-white wires are for the heater, the other two are for the sensor circuit.
If you can tell me which sensor I can get the colors for you.

Hello! I have the wiring to your engine and perhaps a solution...The wire color from the ECM on Connector D pin #7 is White/Green and goes to the O2 sensor...The color at the O2 sensor is Black...White/Blue is connector D pin #1...wire colors that have aged are easily mistaken White looks Yellow with age...connect the O2 sensor to D-7...The O2 sensor is White/Green NOT White/Blue (which looks like Yellow/Blue) this wire is the Check Engine Connector...Tell me how many wires are either cut or misplaced? If we eliminate wiring we can concentrate on why your getting 6 miles /Gal...

If the vehicle backfires or runs poorly My next suggestions are to check the plug wires to be sure they are in the correct place...and #2 to check the timing...the left bank=1, 3, 5 and the right bank=2, 4, 6...Firing order is1, 2, 3, 4, 5, 6...CCW on the distributor...Stick with me and we'll have it purring. see timing below...

I’m happy to help further over the phone at https://www.6ya.com/expert/david_6df67de3b14de867

on my 2006 dodge 2500 hemi my o2 sensor wires got pulled out of conector need help on were the go back in.

your o2 sensor hooks into your exhaust system. where it goes into the exhaust their will be a wire connector somewhere close by unless it melted away or is gone you wont see where it goes into the computer

A new 02 sensor will come with new wires and connector. If not get back with me I think there is a repair kit for that problem.
