Short answer
For a separate sensor, published shop estimates run roughly $120 to $355 including labor (The Drive says $150 to $250, mostly labor; RepairPal estimates $247 to $355 for a 2026 Toyota RAV4). Jerry puts the part alone at about $25 to $100 aftermarket and $100 to $300 OEM. If the sensor is built into an electronic throttle body, Jerry’s figure is $300 to $800 or more.

Why the range is so wide
- Separate sensor or not. This is the big one. Look at your throttle body: a cable to it usually means a separate sensor. TPS vs throttle body shows how to tell.
- Access. On some engines the sensor is right on top; on others intake parts come off first. RepairPal’s RAV4 estimate is mostly labor, while its Cruze throttle body estimate is mostly parts.
- Brand. OEM parts cost more than aftermarket.
- Diagnosis. If the shop has to chase a wiring fault, the bill grows. A sensor is not always the fix: the codes it sets are often wiring.
- Relearn. Some vehicles need scan-tool time after the swap.
The DIY math
For a cable throttle with a separate sensor, the DIY cost is the part plus any tools you lack. A basic digital multimeter and back-probe pins cover the testing; a scan tool with live data helps with codes and the relearn. Jerry puts the DIY job at 1 to 2 hours. Read how to test a TPS first, so you only buy a part you need, then how to replace it.
Ways to keep the bill down
- Read the codes yourself first. Many parts stores read them, or a basic scan tool pays for itself fast.
- Check the connector and wiring before buying anything.
- Ask the shop whether your throttle body has a sensor-only replacement.
- Check for technical service bulletins for your vehicle; OBD-Codes.com puts that first in its P2135 fix list.
Questions people ask
Is it worth replacing a TPS yourself?
On a cable throttle with a separate sensor, often yes: it is usually a plug and two screws, and labor is most of a shop bill. Budget for a meter or scan tool if you do not own one, and for any relearn that needs a scan tool.
Why is labor such a big part of the bill?
Shops charge for diagnosis as well as the swap, and some vehicles need a relearn afterward. Jerry adds about 15 to 30 minutes of labor for the relearn alone.
Why does my quote include a whole throttle body?
On most electronic throttles the position sensors are inside the throttle body and are not sold separately. Some applications do have sensor-only replacements, so ask the shop or check by part number.
OEM or aftermarket TPS?
Both can work. OEM costs more and matches exactly; aftermarket brands such as Standard Motor Products, Delphi, Bosch, Walker, Dorman and Hitachi cost less. What matters most is that the part fits your VIN or matches your old part number.
