434‑3436 High‑Pressure Sensor with Harness for Caterpillar E320C E320D Excavator

434‑3436 Caterpillar high‑pressure sensor with harness and adapter fits E320C and E320D excavators. It transmits hydraulic‑pressure data to ECU to resolve engine‑lugging and weak‑operation problems with imported core and factory‑calibration.

Applicable Models

Fit for Caterpillar Excavator E320C, E320D, installed on main hydraulic pump and control valve.

Technical Parameters

Structure: Extended abrasion‑proof corrugated harness with OEM 3‑pin connector, thread adapter and built‑in O‑ring seal;
Measuring Range:0‑500Bar high‑pressure range conforming to original factory parameters;
Function: It collects real‑time hydraulic high‑pressure data and sends signals to excavator ECU to adjust pump output. Damaged sensor results in weak operation, slow movement, engine‑lugging and fault codes.

Product Advantages

Imported high‑precision sensing core withstands high‑pressure impact and hydraulic‑oil corrosion for rugged construction‑site environments;
Nylon corrugated tube protects wires against pulling and abrasion. Anti‑oxidation pins and matched adapter ensure tight connection and prevent oil‑leakage;
OEM original and aftermarket replacement versions available. Every unit passes pressure‑calibration test before delivery with 3‑12‑month warranty.

Installation Notes

Release residual hydraulic‑system pressure and clean dirt on thread before installation;
Tighten sensor and adapter with standard torque to avoid thread damage, keep the connector waterproof;
Clear fault codes after installation and test‑run the excavator.
