P0501 Fault Diagnosis: 2014 Jeep Wrangler Sahara - Vehicle Speed Sensor Location & Replacement Options

Model: 2014 Jeep Wrangler Sahara Fault Code: P0501 Posted: 2018-10-06 10:54

I own a 2014 Jeep Wrangler Sahara and am experiencing intermittent shifting issues. The vehicle stays in first gear, but when I come to a stop and shift into park or neutral, it sometimes shifts back into drive successfully. The check engine light, ABS light, and tracking lights are all on. The engine light flickers — it works fine for one day before failing again. I'm trying to understand where the P0501 fault sensor is located — is it in the transfer case or transmission? Can I replace this sensor without going through a dealership? Where can I find an affordable replacement part, especially if I'm based in Langley, BC, Canada? The P0501 code indicates a performance issue with the Vehicle Speed Sensor 1. I've already replaced both front and rear wheel speed sensors, but the problem persists. The cruise control is currently non-functional, which I believe may be directly linked to this sensor fault. I'm looking for clear guidance on whether only the sensor needs replacement or if additional components like the valve body must also be replaced.

The P0501 code typically points to a Vehicle Speed Sensor (VSS) located in the transmission. In most 2014 Jeep Wrangler Sahara models, this sensor is inside the transmission, not the transfer case. Replacement may require removing the transmission valve body — so be prepared for that step. Parts can often be found at rockauto.com or other auto parts retailers.

Is it just the speed sensor I need to replace, or do I have to replace the entire valve body and transmission? What does the sensor look like? And where can I buy a genuine replacement without going through a dealership — especially as someone in Langley, BC, Canada?

P0501 - Vehicle Speed Sensor 1 Performance. Are there any other diagnostic codes present? Always use an OBD2 scanner to verify. Have you made any modifications — such as tire or wheel changes? No new tires, same wear pattern. Any off-road activity with frequent spinning wheels? Tire pressure levels?

I previously had P0128 (thermostat) and P0501. I replaced the front right and rear wheel speed sensors, and for a few days the issue disappeared. After five days, the check engine light returned. ABS and tracking lights remain on. Now I have P0128 — which I already knew. I plan to replace that soon. But what about P0501? Is it caused by a transfer case sensor or transmission VSS? Do I need to replace the valve body, or is just the sensor sufficient?

No modifications — this is a stock Jeep with no tire or wheel upgrades.

It's important to check ABS-related diagnostic codes using an OBD2 scanner capable of reading the ABS module. A dedicated scan tool may be necessary for full system diagnostics.

I took it to a dealership with a scanner — they said replace the rear speed sensor. I did that, and then replaced the front right one as well. Afterward, no other codes appeared on my dad’s scanner, and P0501 and P0128 were cleared. The vehicle drives better now, but ABS and tracking lights remain on. Could this be due to a faulty VSS sensor? Since cruise control isn’t working, I suspect the P0501 code is directly related — is that correct?
