Frequently Asked Questions

Q: What is the mating male connector for 368162-1?
A: The mating male plug in the same AMP 3.5mm series is 368161-1 (4-pin male). Verify the male housing part number on your vehicle harness before ordering.

Q: Can a bad MAP sensor connector cause a lean condition?
A: Yes. An open circuit at the MAP sensor connector causes the ECM to lose manifold pressure data and default to a fixed fuel map, typically resulting in a lean condition (P0171) and rough idle under load.

Q: What crimping tool is needed?
A: Use a ratchet crimper rated for 18 AWG (0.5 mm²) AMP 3.5mm terminals – Engineer PA-09 or equivalent precision ratchet crimper.
