TVM TRAVERMAN Mass Air Flow Sensor (MAF) 10393948 — Direct-Replace Hot-Wire, OE Fit for GM V6/V8

TVM TRAVERMAN Mass Air Flow Sensor 10393948 measures incoming air and sends a precise airflow signal to the engine computer so your fuel delivery and throttle response return to factory-like behavior.

Designed as a direct-replacement MAF for many GM V8 and V6 applications, this sensor uses a hot-wire element and sealed electronics to produce steady, factory-style airflow readings. It’s engineered to match OEM electrical and mechanical specs so the engine control unit gets accurate data across temperature and flow ranges. The result is reduced hesitation, improved idle stability, and restored drivability when a worn or failing MAF has been causing performance issues.

How will this MAF sensor change how my vehicle runs?

Replacing a degraded MAF can immediately correct incorrect air-fuel calculations that lead to rough idle, stumbling under load, and poor throttle response. Because the sensor provides the ECU with reliable airflow numbers, the engine can deliver fuel more accurately and rev smoothly.

• Stabilizes idle and reduces stalling or hunting RPMs
• Improves throttle response and reduces hesitation under acceleration
• Helps restore expected fuel economy by correcting mixture errors
• Reduces recurring check-engine lights tied to airflow faults

Which vehicles and part numbers is this compatible with?

This MAF is intended to fit a broad range of GM trucks and SUVs from late-2000s to mid-2010s. It lists common OEM cross-references so installers can verify fitment against factory part numbers.

• Chevrolet: Silverado 1500/2500HD/3500HD, Tahoe, Suburban, Avalanche (2009–2015 as noted)
• GMC: Sierra 1500/2500HD/3500HD, Yukon, Yukon XL (2009–2015 as noted)
• Cadillac: Escalade, Escalade ESV/EXT, CTS (2009–2015 where applicable)
• OE cross-refs: 10393948, 23256991, AF10060, MAF300, 917-1067, 5S13836

Is installation difficult and do I need programming?

Most installations are straightforward and require only basic hand tools; the sensor mounts between the airbox and intake tube and uses the factory electrical connector. In nearly all listed applications no special programming is required — the ECU adapts once the battery and connector are reattached.

• Disconnect battery, unplug MAF connector, loosen clamps and remove old unit
• Install new sensor in the same orientation, secure clamps, reconnect wiring
• Reconnect battery, allow brief idle to let ECU adapt, then test-drive
• Scan for codes if check-engine light persists; many issues clear after replacement

What construction and testing standards does this sensor meet?

Built to meet or exceed OEM expectations, this MAF features a calibrated hot-wire element, rugged housing to resist heat and vibration, and sealed electronics to protect against moisture and contaminants. Each unit undergoes 100% testing to confirm response time and output accuracy before shipment.

• Precision-calibrated sensing element for consistent signal across conditions
• High-strength housing resists engine-bay heat, vibration and chemicals
• Sealed electronics reduce failure from moisture and dust ingress
• Individual testing minimizes return rates and intermittent drivability issues

Who is this for? If your Chevy, GMC, or Cadillac from the compatible model years shows rough idle, hesitation, unstable RPMs, or a stored airflow-related trouble code, this TVM TRAVERMAN MAF 10393948 is a direct-fit replacement engineered to bring airflow readings back within expected ranges. It’s aimed at DIY mechanics, independent shops, and fleet technicians who need a reliable, OEM-equivalent sensor that installs quickly and restores normal engine behavior without complicated programming.
