If the reading fluctuates or drops out during wiggling, the connector is the fault – not the sensor. A stable reading that is simply out of range indicates a failed sensor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: What crimping tool is needed for 1.5mm GM terminals?\u003c\/strong\u003e\u003cbr\u003eA: Use the Kent-Moore J-38125-8 or Delphi 12085271 ratchet crimper for 1.5mm Micro-Pack 100 terminals.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: Can I use 13898956 for both CTS and oil pressure sensor applications?\u003c\/strong\u003e\u003cbr\u003eA: Yes. The 13898956 housing is used for multiple 2-pin sensor applications across GM platforms.
