Hyundai / Toyota Camry 2-Pin 2.0mm Intake Air Temperature Sensor Connector – OEM MG640461-5
Direct OEM-specification replacement for the 2-pin wire harness connector used on intake air temperature (IAT) sensors across Hyundai and Toyota Camry platforms. Cross-references OEM part number MG640461-5. Uses the 2.0mm contact series in black nylon housing — the IAT sensor connector is located on the air intake pipe or air filter housing, where it is exposed to heat from the engine bay and vibration from the intake system.
The 2-pin IAT sensor connector is located on the intake air pipe, connecting the intake air temperature sensor to the engine control module (ECM). A failed connector causes the ECM to lose intake air temperature data, triggering P0110–P0113 (IAT sensor circuit) fault codes. Without IAT data, the ECM cannot accurately calculate the air density for fuel injection, causing the engine to run rich in cold conditions and lean in hot conditions — increasing fuel consumption and emissions. The IAT connector is also frequently damaged during air filter replacement or intake system modification.

Q: My car has a P0112 IAT sensor low voltage fault — could it be the connector?
A: Yes. A short circuit or corroded 2-pin IAT sensor connector is a common cause of P0110–P0113 faults. Test the sensor resistance first (typically 2–20kΩ depending on temperature) — if it is within specification, the fault is in the connector or wiring.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
