Frequently Asked Questions

Q: Are 6188-4920 and 90980-12719 the same connector?
A: Yes. 6188-4920 is the Yazaki manufacturer part number; 90980-12719 is the Toyota OEM service catalog number for the same connector. When ordering from a Toyota dealer, 90980-12719 is the correct reference. Both are fully interchangeable.

Q: What causes P0340 on Toyota Corolla?
A: P0340 (Camshaft Position Sensor Circuit) on Toyota is most commonly caused by a failed CMP sensor, a corroded or loose 3-pin connector (6188-4920), or a broken reluctor ring. Always inspect the connector before replacing the sensor – a corroded connector produces identical symptoms to a failed sensor at a fraction of the cost.

Q: What crimping tool is needed for Yazaki terminals?
A: Use a ratchet crimper for 0.5mm² (18 AWG) Yazaki terminals – the Hozan P-706 or Engineer PA-09 are commonly used for this terminal series.
