2007 dodge caliber output speed sensor location

Hi
Does anyone know what purpose the right rear (passenger side) speed sensor has, it is located on the rear passenger side hub/bearing assembly.

I have to replace the left rear hub and figured I would do them both at the same time, the left has no sensor so I ordered the part for both sides and found the sensor in the process of removing the hub on the other side. There was no indication from the part store that there were 2 different rear hubs for this car, and the dealer said there should not be any sensors on this vehicle according to the options and lack of ABS. I have a 2007 SXT, 5 speed, 1.8l with no ABS or cruise control, just wondering if this is installed at the plant just in case of various options or if it actually does something in this car, because the new hubs do not have the sensor, and was going to leave it disconnected.

Any help would be appreciated.

Thanks

Good evening,

I found these pictures in the service manual (attached).

Maybe the manual will be more specific regarding the Calibers that don't have ABS. You can download yours here:

I will continue to search in the manual for some text about it ... if i find something all post back.

Best Regards

From page 620. Only for ABS.

Since I'm not a mechanic, I'm not comfortable to tell you to let the cable unplug. :shy:

Maybe our tradesmen from the mechanic field can reinforce the documentation I'm finding in the manual.

Basically, i can only find information on the sensor in the ABS section of the manual ... for now ... still looking ...

Well it's the best i can do

Hope your well started in your information quest. I'll be following the thread to learn more.

Are you sure you dont have ABS?

The ABS control unit is located on the passenger side firewall under the hood.
It has a metal valve block with a motor and several metal tubes and cables connected to it.
If you have a CVT, there is a good chance you may also have ABS, not sure about a 5 spd however, but you should have two sensors, one on each rear wheel.

Also, during startup, if you see the ABS lamp on the dash light up, this would indicate you have ABS.

Without knowing the exact situation, I would replace the hub assembly with one that has a sensor and connect the cable.

Thanks Francois
I have the manual too, I figure since there is no ABS or cruise and when I spin on ice my speedo goes up to 100, it probably does nothing, even the dealer was surprised that there was a sensor, they figured they put them on every car even if down the line the car doesn't get ABS or cruise control. I guess I will leave that hub on and drive it without the sensor attached and see what happens.

Hey Dave K
Yes have CVT but no ABS at all, aparently my wife opted out completely, very few cars have no ABS at all. I am going to try the start up trick, didn't think about that, thanks. I'll see what error codes, if any, it produces without the sensor connected.
Thanks again

The top drawing on this page shows the ABS unit and where it is located.

Yeah, nothing like that under my hood, went and did the start test, no error codes generated, runs and starts fine, up on blocks waiting for replacement hubs. Only thing I noticed was the warning light for the Electronic Throttle Control Indicator lit up for longer than any other light to turn off, not my car so I don't really know if this is new or normal, wife never noticed either.
No test drive until new hubs are in

Any chance what he is looking at is the tire pressure
monitor receiver? Those Calibers with the system have
one rcvr on each front wheel and only one on th rear
as far as I know.

I think you maybe right on with that.

HI everyone
Dealer says it is the speedometer sensor, because it is a standard transmission, but living up near the arctic and having spun the tires on ice and watching the speeometer go to 80 kph while standing still, I think they may be wrong given it is a FWD vehicle. Still waiting for the hubs to arrive and will post my findings once I drop it down and take it for a spin.

The dealer maybe right. The sensors on this car are a plenty and knowing when the tires are spinning is required due to the ETC. One way to determine that is to have a speed sensor on the drive wheels as well as at least one non-drive wheel.

Hi Prop1
ETC being tranction control? I don't have that either, I blocked the front axles up too and the speedo works, bizarre, maybe just redundant in case something needed the info

We don't have tps(tire pressure monitoring) either, anyone have a pick of what that looks like on the right rear hub?

ETC= Electronic Throttle Control. It needs that wheel info in order to know how far to open the throttle plate. And it's on all Calibers, and probably 99% of cars from the last 5 years.

Before tearing your Caliber a part, you should have spent some time with the service manual. Working on these cars without having spent some time with the service manual is like driving down a dark lonely country road with your lights off.

From what I can tell on the wiring diagram (8W-35-4), the only place any wheel speed sensors show up is directly wired to the ABS module.

So to me at this point, the lone rear wheel sensor is still a mystery.

The "vehicle speed sensor" is directly associated with the transmission,even on a manual. On the CVT the output speed sensor serves the same purpose.

Also, looking at the mechanical section on brakes - no wheel sensors are shown or mentioned in the section on "base" (non-ABS) brakes.

Actually, the speed sensor is integrated into the hub and info is in section 2 of the service manual. On Calibers without ABS, the sensor is only on the right rear hub. Sorry to say it, but I was right on this one.

Interesting - that's what is so great about this forum.
We start kicking something around a bit, and we eventually learn the correct answer.

Yeah, this car is an oddity, opened up the interior to trace the wire and found it runs to a harness connector which has open tabs where this sensor's wires attach, and the wiring for another sensor(same connector, no wiring through body to the hub) at the exact same spot on the drivers side, which also has empty tabs where the wires attach, so I think it does nothing. chirped both lines and they go no further than this connector.
Dealer gave me part numbers and I got them 10 times cheaper online, I had to inform them of the sensor, which they said should not be there. So maybe there are mods done on the fly during assembly, this is one of the first calibers ever built so maybe they ironed out a few items during production, I'm sure it was a base base model to be used as a demo so people would order the abs/tcs/cruise and auto tranny based on this one. He says there are only 2 in canada with the exact options(or lack of) as my car, US models are different, so he says.
So i guess everyone is right, car is just wrong- literally - hahaha
