What should I check before buying and installing?

Confirm the part number and make/model/year/engine match your vehicle. Inspect the old sensor’s connector shape and mounting pattern; mismatches mean this unit won’t fit. If your vehicle thrown codes reference MAF, ensure the problem isn’t wiring or intake leaks before replacing.

• Compare your old sensor’s part number and connector to the replacement list.
• Scan for diagnostic trouble codes and test MAF output when possible.
• Check intake tubing, vacuum lines, and sealing surfaces for leaks or damage.
• Disconnect the battery and follow safe procedures when swapping electronic sensors.
