Frequently Asked Questions

Q: What causes throttle position sensor connector failure on Mitsubishi Lancer?
A: Common failure modes include terminal corrosion from engine bay moisture, wire chafing at the connector entry, and terminal push-back from vibration. A faulty TPS connector can cause rough idle, hesitation, and engine management warning lights.

Q: Is the PB185-04326 compatible with aftermarket throttle position sensors for Mitsubishi?
A: Yes, provided the aftermarket TPS uses the same 4-pin 3.5mm connector interface. Verify pin count and wire gauge against your sensor’s datasheet before installation.
