Saturn Aura Throttle Position Sensor Connectors

Saturn Aura Throttle position sensor connectors

Starting at low prices, AutoBuffy stocks multiple throttle position sensor connectors from top OE-quality brands for the Saturn Aura. This pigtail connector links the throttle position sensor to the ECU, transmitting throttle angle data so the engine can meter fuel and air correctly. A cracked, corroded, or broken connector disrupts that signal, triggering driveability problems that often mimic a failed sensor itself.

Signs your Saturn Aura needs a new throttle position sensor connector

  • Intermittent or steady check engine light with TPS-related codes such as P0120–P0124 or P0220–P0229
  • Erratic or surging idle that worsens when the wiring harness is flexed or the engine vibrates
  • Hesitation or stumble on acceleration, especially from a stop, as the ECU receives a broken signal
  • Unexpected engine stalls at low speed or when coming to a stop at a traffic light
  • Reduced throttle response or the vehicle entering limp mode and limiting engine output
  • Visible corrosion, melted plastic, spread terminals, or broken locking tabs on the existing connector body

Which throttle position sensor connector should you buy for your Saturn Aura?

The main decision is whether to buy an OE-spec replacement pigtail that matches the original terminal count and housing geometry, or a universal repair connector that requires more lead splicing. Secondary considerations are terminal material and whether the connector comes pre-loaded with terminals and weatherproofing seals, which affect long-term corrosion resistance.

OE-spec direct-fit pigtail
Best for
Fastest, cleanest install with no terminal guesswork
What you get
Exact housing shape, correct terminal count, pre-installed weather seals, and a short lead wire ready to splice
OE-spec pigtail with TPA (terminal position assurance) clip
Best for
High-vibration applications or vehicles with a history of connector issues
What you get
All direct-fit benefits plus a secondary locking clip that prevents terminal back-out under heat and vibration
Universal repair connector / metri-pack kit
Best for
Situations where the OE-spec pigtail is unavailable or budget is the priority
What you get
Generic housing with loose terminals you crimp yourself; requires matching terminal gender and cavity count to the original
Connector with pre-tinned, heat-shrink leads
Best for
DIYers who prefer solder splicing over butt connectors
What you get
Slightly longer leads with pre-tinned wire ends and adhesive-lined heat-shrink tubing included for a moisture-resistant joint

Replacing a throttle position sensor connector on a Saturn Aura

Easy⏱ 30–60 minutesWire stripper and butt-connector crimping toolElectrical contact cleanerDielectric greaseScan tool or OBD-II reader to clear codesTrim removal pick or small flathead screwdriver to release the connector lock tab

Disconnect the battery negative terminal, then release the locking tab on the original connector and unplug it from the TPS. Cut the damaged pigtail leads back to clean wire, strip the new pigtail leads, and splice them to the harness using weatherproof butt connectors or solder and adhesive-lined heat shrink — matching wire color to wire color. Apply a small amount of dielectric grease to the terminal cavity, plug the new connector in until it clicks, reconnect the battery, and clear any stored fault codes before road-testing.

Frequently asked questions

How much does it cost to replace throttle position sensor connectors on a Saturn Aura?
The connector pigtail itself starts at low prices on AutoBuffy. A shop will typically bill 0.5–1 hour of labor on top of the part cost, making the total repair modest compared to replacing the entire TPS. Doing it yourself keeps the cost to just the part and any splice supplies.
Can a bad connector cause the same codes as a failed throttle position sensor on a Saturn Aura?
Yes. The ECU cannot distinguish a failing sensor from a broken circuit feeding it. TPS range, performance, and rationality codes — typically in the P0120–P0229 range — will set whether the fault is inside the sensor or at the connector. Always inspect and wiggle-test the connector before condemning the sensor itself.
Is it better to replace just the connector or the entire TPS on a Saturn Aura?
Replace only the connector if the sensor tests within specification and the connector shows obvious physical damage — corrosion, spread terminals, or a broken lock tab. If the sensor also reads erratically on a scan tool after the connector is repaired, replace both together to avoid returning to the same job twice.
How do I know which throttle position sensor connector fits my Saturn Aura?
Match by the number of cavities (terminals), the connector body style, and the terminal gender visible on the sensor itself. For the Saturn Aura, the correct fit is confirmed using the year, engine size, and sometimes transmission type. Entering your full vehicle details on AutoBuffy filters results to connectors verified for your application.
Can I repair the existing connector instead of replacing it on my Saturn Aura?
Minor corrosion on intact terminals can sometimes be cleaned with electrical contact cleaner and treated with dielectric grease. However, spread terminals, cracked housing, or melted plastic compromise the connection permanently. A replacement pigtail costs little and eliminates the risk of a recurring intermittent fault caused by a structurally compromised housing.
Do I need to reprogram or reset anything after replacing the throttle position sensor connector on a Saturn Aura?
Swapping only the connector requires no reprogramming. After reconnecting, clear any stored fault codes with a scan tool and perform a short test drive to confirm the codes do not return. Some engines benefit from a throttle body relearn procedure — consult your service information to see if the Saturn Aura requires one.
