New crankshaft position sensor connector plug for Nissan QR25DE 2.5 L4 engines (may fit other applications – please look closely at the pictures). Connector will fit oem sensor part number 237316N21A. This is a locking type connector – to see how these work go to Youtube and search “Nissan & Infiniti Cam and Crank Sensor connector Lock”. Sometimes these connectors are broken during removal because people are unfamiliar with the locking action of the connector. Often the oem connector goes bad due to improper crimping of the wires on the terminals during assembly. A bad connector will often throw a P0335 + P0725 code. Our connectors are hand assembled in the USA and tested. We only use the best quality Pigtail wires - GXL automotive wire with Cross-Linked Polyethylene (XLPE) insulation material (SAE Spec J-1128, meets or exceeds Ford Spec M1L-123A,  Chrysler Spec MS-8288 and Delphi spec). Conductor material is 100% copper. Beware of other vendors selling these connectors with non-automotive grade PVC insulated wire – this type of wire does not belong in an engine compartment of a modern automobile. Inferior PVC insulated wire does not have anywhere near the thermal, oil and solvent resistance of Cross-Linked Polyethylene (XLPE) insulated wire. If you hold a PVC insulated wire to the flame of a lighter for a few seconds it will quickly melt and burn leaving a charred black brittle residue. XLPE insulated wire will easily withstand this flame test and retain its insulating properties and flexibility. Pigtail wires at 8+ inches long. Free shipping within the USA.
