3-Pin Waterproof Idle Motor & Intake Pressure Sensor Connector – Suzuki OEM PK605-03027

Direct-fit replacement for Suzuki OEM part number PK605-03027, a 3-pin IP68 waterproof female connector used for idle air control (IAC) motor, intake manifold absolute pressure (MAP) sensor, and throttle body harness connections on Suzuki vehicles. The rubber wire seals maintain IP68 integrity in the high-heat engine bay environment.

Idle Motor / MAP Sensor Pin Assignment (3-Pin)

Note: Verify pin assignment with Suzuki-specific wiring diagram before installation.

Compatible Suzuki Applications

• Suzuki Swift (ZC/ZD, 2004–2010): IAC motor and MAP sensor harness connector
• Suzuki SX4 / Aerio: Throttle body and intake pressure sensor connector
• Suzuki Grand Vitara (JB): Idle air control and MAP sensor harness connector
• Suzuki Jimny (SN): Throttle body and intake sensor harness connector

Idle Motor vs MAP Sensor – Same Connector, Different Functions

The PK605-03027 connector is used for both the idle air control (IAC) motor and the MAP sensor on Suzuki platforms because both components use the same 3-pin housing format. The IAC motor controls idle speed by regulating air bypass around the throttle plate; the MAP sensor measures intake manifold pressure for fuel injection calculation. A corroded connector on either component will cause idle instability or incorrect fuel trim.

Diagnosis – Idle and MAP Sensor Faults

• P0505–P0507 (IAC Circuit): Inspect PK605-03027 connector before replacing IAC motor – a corroded terminal is a common root cause of idle speed faults on Suzuki
• P0105–P0108 (MAP Circuit): Check connector integrity – a damaged wire seal allows moisture ingress and causes intermittent MAP signal faults
• Rough idle / stalling at warm-up: A corroded IAC connector prevents the ECU from controlling idle air bypass, causing the engine to stall when the throttle closes

FAQ

Q: Is PK605-03027 for the idle motor or the MAP sensor?
A: PK605-03027 is used for both on Suzuki platforms – the same 3-pin connector housing is shared between the IAC motor and MAP sensor. Confirm which component you are replacing before ordering.

Q: Can a bad idle motor connector cause stalling on a Suzuki?
A: Yes – a corroded or open-circuit PK605-03027 connector prevents the ECU from controlling the IAC motor, causing the engine to stall when idle air bypass is needed (e.g., at warm-up, A/C load, or deceleration).
