Toyota 3-Pin Camshaft Position & Output Shaft Sensor Connector – OEM 6189-0734
Direct OEM-specification replacement for the Toyota 3-pin connector used on camshaft position (CMP) sensors and automatic transmission output shaft speed sensors. Cross-references Sumitomo OEM part number 6189-0734. Available bare or with 15cm pre-wired leads.
| Pin | Function | Failure Symptom if Corroded |
|---|---|---|
| 1 | +5V reference voltage from ECU/TCM | P0340 (CMP) or P0720 (output shaft) — circuit low |
| 2 | Signal output to ECU/TCM | Erratic cam timing or transmission shift faults |
| 3 | Signal ground / return | Sensor reads max voltage — circuit high fault |

Q: My Toyota automatic transmission shifts erratically and has P0720 — is it the connector?
A: P0720 (output shaft speed sensor circuit) on Toyota automatics is frequently caused by a corroded 3-pin connector at the transmission output shaft sensor rather than a failed sensor or TCM. Inspect the connector before replacing the sensor.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
