• 100% re-solder of critical components ensures superior electrical connections, no intermittent failures and longer product life
• On-car vehicle validation routines ensure that modules meet all form, fit, durability and performance requirements
• All modules are 100% tested with automated computer test equipment to ensure full functionality and reliability
• Sensors precisely track O.E. output curves and maintain spec tolerances to ensure accurate feedback to the vehicle’s engine control management system
• Components are rated to handle demanding temperature variations for optimum reliability in every environment

Check for Vacuum Leaks First!

Vacuum leaks present symptoms similar to a faulty MAF Sensor. When replacing the MAF, always check for vacuum leaks, too. Common sources include:

• Cracked or loose Vacuum Hoses / Connectors - an audio Stethoscope can help detect air induced sounds from vacuum leaks.
• Leaking Intake Manifold Gasket (found in the "Engine" category) - Vacuum Gauge readings below 17-22 in-Hg (normal manifold vacuum at sea level) at idle may indicate an intake manifold gasket leak.
• Note: As elevation increases, readings decrease. Subtract 1 in-Hg from normal manifold vacuum reference for every 1,000 feet increase in elevation above 2,000 feet.
• Stuck open PCV Valve - remove the PCV Valve and gently shake it; if it does not rattle, the valve is clogged or dirty and should be replaced.
• Cracked Intake Boot (found in the "Engine" category)
