Where is the speed sensor on a 2007 Dodge Caliber?
The 2007 Dodge Caliber’s speed sensor is mounted on the transmission tailshaft, on the passenger side of the vehicle, and uses a three-wire connector
This little guy’s officially called the Vehicle Speed Sensor (VSS). It screws right into the transmission housing and tracks the output shaft’s rotation to feed speed data to both the PCM and your instrument cluster. (Pro tip: Always pop the negative battery cable before diving in—no one wants a surprise electrical short.) You’ll find it tucked low, so expect some transmission fluid to drip out when you loosen it.
Where is my speed sensor located?
On most Dodge Calibers, you’ll find the speed sensor near the front or rear of the transmission housing, depending on whether it’s the input or output shaft sensor
Your best bet? Grab a repair manual or fire up a service info system to figure out which sensor you’re after. (Spoiler: It’ll probably leak a little ATF when you pull it out, so keep a drain pan handy.) These sensors usually have a threaded body, a wiring pigtail, and an O-ring seal to keep things tidy.
What are the symptoms of a speed sensor going out?
Common signs include erratic or inoperative cruise control, harsh or delayed shifting, and a Check Engine Light with codes P0500, P0720, or P0725
You might also notice your speedometer acting like a drunk driver—bouncing around or just flatlining to zero even when you’re moving. Worst case? Your transmission could slap itself into “limp mode” because the PCM’s flying blind without solid speed data. If you're experiencing these issues, you may want to check out how to interpret speed-related data for troubleshooting.
Where is the left front wheel speed sensor located?
The left front wheel speed sensor is mounted near the brake rotor on the front left wheel hub assembly, as part of the ABS system
It’s basically a magnetic nose that sniffs the tone ring (also called a reluctor ring) bolted to your CV joint or wheel hub. This thing talks to the ABS module—and sometimes the traction control system—to keep your brakes and stability in check. If you're curious about how speed affects other systems, you might find this explanation of speed dynamics helpful.
Is it hard to replace a speed sensor?
Replacing a speed sensor is straightforward and one of the easier do-it-yourself jobs; most DIYers can complete the job in under an hour with basic tools
All you really need is a socket set, some jack stands, a drain pan, and maybe a multimeter if you’re feeling fancy. (Don’t forget to swap out that O-ring and slather a thin coat of fresh ATF on the seal before you button it back up.) For more on sensor repairs, see this guide on sensor maintenance.
Can I drive my car with a bad speed sensor?
You should not drive your car with a confirmed bad speed sensor, especially if the speedometer is inoperative or the transmission is shifting poorly
Rolling around with a dud sensor isn’t just annoying—it’s dangerous. You could lose cruise control, get weird braking behavior, or even toast your transmission from wonky shift timing. If your ride’s stuck in limp mode, call a tow truck. No questions asked. To understand why speed matters in driving safety, read this article on speed consistency.
What makes a speed sensor go bad?
Common causes include chafed or corroded wiring, a failed internal circuit, or magnetic contamination from metal debris clinging to the sensor tip
Years of heat, vibration, and fluid leaks slowly murder the internals. Before you replace anything, give the wiring harness and connector a good once-over—corrosion or frayed wires often sneak up and cause all the trouble.

How much does it cost to fix a speed sensor?
Expect to pay $25 to $45 for the part and $120 to $250 for labor, depending on location and shop rates
Dealerships love to charge an arm and a leg, but independent shops usually cut you a better deal. If you’re feeling handy, buy the OEM or a solid aftermarket sensor (Mopar part # 68038397AA) and do it yourself—saves a ton of cash.
Can a speed sensor be cleaned?
Yes—you can clean the sensor tip and reluctor ring with brake cleaner or electrical contact cleaner if corrosion or dirt is the suspected cause of failure
Avoid anything abrasive—wire brushes and sandpaper are a one-way ticket to sensor suicide. Once it’s sparkling, check the resistance with a multimeter before you put it back in service.
Can ABS sensor cause transmission problems?
Yes—if an ABS wheel speed sensor fails or sends erratic signals, it can trigger false transmission shift points or torque converter lock-up issues
That’s why scan tools often cough up both ABS and transmission codes at the same time. Don’t ignore those ABS warnings—left unchecked, they can turn into drivability nightmares and even safety hazards.
How long does it take to replace speed sensor?
A professional technician typically completes the replacement in 2 to 3 hours, including test-driving and relearning procedures
Shade-tree mechanics with some experience can usually knock it out in 45 to 90 minutes. After you’ve buttoned everything up, clear the codes and take it for a spin to make sure everything’s playing nice again.
