If the TPS is integrated into the throttle body, the bill is higher due to the assembly and calibration. In high-labor-rate markets (major metros and coastal cities), estimates trend toward the upper end.

Real customers Jerry helped
While pricing can vary based on different factors like location, parts used, and exact vehicle, Jerry uses real customer experiences to show what drivers are paying right now. Here are some examples of customers we’ve helped find their repairs at the right price.
Estimates are modeled based on real vehicle and location data; names have been changed. Actual prices will vary by shop, parts, and vehicle condition.
Cost summary
Symptoms of a failing TPS
Jerry customers find that bad TPS often triggers the Check Engine Light and causes drivability issues: rough or high idle, hesitation or stalling on acceleration, poor/erratic shifting in automatics, and low power or failure to accelerate. These overlap with other faults; when in doubt, book a diagnosis to confirm.
Cost breakdown: why prices vary
Jerry customers are seeing prices vary based on a few key factors:
System design (integrated vs. standalone):
Biggest variable. Standalone sensors are $50–$150; integrated ETBs run $300–$800+ and may add relearn time.
Parts sourcing (OEM vs. aftermarket):
OEM sensors are $100–$300; quality aftermarket are $25–$100. Stick with reputable brands (Denso, NTK/NGK, Delphi, Bosch). For ETBs, be cautious with remans unless they specify new sensors/motor.
Labor & access:
Independent shops are often $90–$160/hr; dealers are higher. Easy sensors: ~0.4–0.8 hr; ETBs: ~0.6–1.5 hr.
Calibration:
Many cars need a throttle/idle relearn, adding ~0.2–0.5 hr. Some models relearn with a key-on/idle routine, but guided procedures are more reliable.
Other line items:
Diagnostic fee ($120–$200) and supplies/cleaning ($10–$40).
These ranges come from Jerry’s national database of real repair invoices. To see localized pricing and live quotes, download the Jerry app.
The repair explained: your engine’s “gas pedal” sensor
The TPS sends a signal to the ECU which uses the throttle plate’s angle to calculate driver intent. The ECU then manages fuel, ignition timing and automatic transmission shift points for smooth, efficient performance.
Setups differ, so identify yours:
- Cable throttle (often older): A standalone TPS bolts to the throttle shaft and can be replaced by itself.
- Drive-by-wire (most modern): TPS is built into the electronic throttle body (ETB) and typically isn’t sold separately. There’s also an accelerator pedal position (APP) sensor that can cause similar symptoms.
Check your VIN in a parts catalog to confirm standalone TPS vs. complete throttle body. Not sure? A quick professional diagnostic can confirm.
Your action plan
Confirm the diagnosis:
Describe symptoms clearly to a tech who can test throttle body/pedal sensors and wiring. Jerry’s diagnostic tool can also provide guidance.
Assess difficulty:
Use VIN/parts lookup to learn whether you have a standalone sensor or ETB and whether a relearn is required.
Get competing quotes:
Quotes will vary based on the following considerations: Is my TPS standalone or integrated? Flat-rate time or hourly rate? Will you perform/document the relearn and road test? What brand part and what warranties? Is there a diagnostic fee?
Check warranties:
See if any powertrain/emissions coverage applies by VIN; otherwise confirm the shop’s warranty in writing.
DIY vs. Pro: what to expect
Jerry offers price point comparisons on parts and labor to help customers decide on the right approach:
A few considerations before you dive in:
- Tools: Basic hand tools (sockets/Torx), in-lb torque wrench, throttle-body-safe cleaner, service manual for torque specs/procedures.
- Safety/Fit: Don’t pry an electronic throttle blade; use new gaskets; fully seat and latch connectors; keep cleaner off motor/electronics.
- Hand it to a pro if: Let a pro handle this if a relearn procedure is required, connectors are corroded, plastics are brittle, or the job requires removing a complete ETB.
- Relearn basics (generic): Battery disconnect 10 min → reconnect → key-on 30 sec (no pedal) → start and idle to warm → three gentle 2k-rpm blips → 5-min idle. If idle hunts/stays high, a guided relearn is needed.
A simple bolt-on sensor with no complex calibration is a good DIY option. Integrated throttle bodies or vehicles requiring a guided relearn, however, are best left to a pro. Price both paths in the Jerry app and choose what makes sense.
After any work near the air tube or throttle, it’s worth doing two simple things: count your clips and screws to make sure they aren’t missing, and take a quick look inside the tube to check that the air path is clear. If the tube’s open while you’re working, plug it with a clean, brightly colored rag so nothing falls in—and make sure you pull the rag before you button everything back up. Little habits like that can prevent a small oversight from turning into a roadside headache.
Related repairs & services
Jerry customers are bundling these repairs with work on the TPS:
- Induction carbon cleaning: Throttle body cleaning is smart preventive maintenance (use throttle-body-safe cleaner; don’t soak the motor).
- MAF/vacuum/APP checks: These can mimic TPS issues; a shop can verify quickly.
- Harness/connector inspection: Many “bad TPS” cases are wiring, grounds, or corrosion—wiggle tests and terminal checks can prevent unnecessary parts.
- Cooling system service: Some throttle bodies are coolant-heated; top off/refill if opened.
Platform notes:
- GM: Carbon-stuck plates can cause stalling/poor response; cleaning + relearn often restores behavior.
- Nissan: Idle learn procedures are picky—follow the precise sequence.
- Toyota (Denso ETB): Don’t force the blade; light cleaning only due to coating.
- Hyundai/Kia: Some models relearn after a battery reset and idle period; others need a guided relearn.
Not sure what you need? Shops can provide details—brands used, book time, and any relearn fee should be spelled out.
