Complete Guide to Chevrolet Spark 2016-2022 1.4L Throttle Body Replacement & Maintenance

Your Chevrolet Spark's throttle body decides how much air reaches the 1.4L engine every second you drive. When it sticks, fouls up, or fails, you feel it through the pedal: rough idle, hesitation, stalling, and a check engine light that keeps coming back. This guide covers the symptoms, the exact specifications, real replacement costs, and the full swap procedure for 2016-2022 Spark models.

Already know what you need? Our throttle body for the 2016-2022 Chevrolet Spark 1.4L is engineered to meet or exceed OEM specifications and replaces factory part numbers 673055, 12654237, and 12673014.

What a Throttle Body Actually Does

A throttle body is a butterfly valve that meters air into the engine. It takes input from the accelerator pedal and a network of sensors, then opens to precisely the angle needed for the power you're asking for at that moment.

Your Spark runs an electronic unit. A small motor opens and closes the butterfly valve on commands from the Engine Control Module (ECM). Compared with old cable-operated setups, that design delivers smoother acceleration, better fuel efficiency, and reduced emissions.

Match these numbers against your old unit before you order. If the OEM numbers on your original assembly line up, the replacement throttle body for the 2016-2022 Spark 1.4L is a direct fit.

Seven Warning Signs Your Throttle Body Is Failing

Catch these early and you avoid a tow. Watch for:

• Rough idling: the engine runs unevenly or stalls at idle.
• Poor acceleration: sluggish response when you press the accelerator.
• Check engine light: illuminated with throttle body-related codes.
• Stalling: the engine dies unexpectedly, especially at low speeds.
• Reduced fuel efficiency: a noticeable drop in miles per gallon.
• Erratic RPM: engine speed fluctuates without any driver input.
• Poor performance: an overall lack of power and responsiveness.

Any single symptom can point elsewhere, but a cluster of them — rough idle plus stalling plus a throttle code — almost always lands on the throttle body. Treat stalling at low speeds as urgent; it's a safety issue in traffic, not just an annoyance.

What Throttle Body Replacement Costs

Professional replacement for this job isn't cheap. The major published estimates run:

• YourMechanic: $352 total — $212 in parts plus $140 in labor.
• RepairPal: $303-$335 total, with $61-$90 of labor plus parts.
• 2019 Spark, model-specific: $302-$330 total.

You can shrink that bill two ways. Buy the part yourself and pay a mechanic only for the install — labor accounts for $61 to $140 across those estimates — or do the whole job in your driveway. Our Chevrolet Spark throttle body also saves up to 50% compared to dealership part pricing, so the math works whether you wrench yourself or hand it to a trusted mechanic.

How to Replace the Throttle Body, Step by Step

The physical swap is straightforward with basic hand tools. Work through it in this order:

1. Disconnect the negative battery terminal for safety.
2. Remove the air intake duct and filter housing.
3. Disconnect the electrical connectors and vacuum lines.
4. Remove the mounting bolts securing the throttle body.
5. Install the new throttle body assembly.
6. Reconnect all electrical and vacuum connections.
7. Reinstall the air intake components.
8. Reconnect the battery and perform the throttle body relearn procedure.

The step people forget: after installation, most modern vehicles require a throttle body relearn using a professional scan tool so the ECM properly calibrates the new component. Basic hand tools handle the physical work — plan for scan tool access before you start.

On timing: most professional mechanics complete the job in 1-2 hours. A DIY install with moderate mechanical experience runs 2-3 hours, with the extra time going to double-checking connections and the relearn.

Cleaning vs Replacing: What Each One Fixes

Cleaning is real maintenance, not a stopgap — but it only solves one problem. Follow these rules:

• Frequency: clean every 30,000-50,000 miles, or as soon as symptoms appear.
• Cleaner: use only throttle body-specific cleaners — never carburetor cleaner.
• Method: remove the throttle body and clean it thoroughly, paying special attention to the butterfly valve edges and the bore.

Cleaning resolves issues caused by carbon buildup. If the electronic components or mechanical parts inside are damaged, no cleaner brings them back — that's when a replacement unit is the fix.
