Overview 

The KHR2433 is a two-wire negative temperature coefficient (NTC) thermistor sensor catalogued across Sumitomo, CASE, Link-belt and New Holland excavator as a temperature sensor for water and hydraulic oil temperature. It is a applicate to Case CX series excavators CX130

to CX800, Sumitomo SH series excavator SH120 to SH800. Although the user query associates it with “Isuzu engine,” the KHR2433 is not an engine-management sensor in the strict sense — it is a machine-side hydraulic oil / coolant temperature sensor used on excavators powered by Isuzu engines (including the 6UZ1 Tier 4B and 4LE2 series). Its signal is read by the machine controller/ECU for hydraulic oil temperature monitoring, overheat protection, and display instrumentation, rather than by the engine ECM for fuel or boost control. Interchange numbers documented for KHR2433 include 179730-0020, 179730-0010, 179730-0040, R61540090005, 811001744, 168135A1, 47759463, 3DA1223.

Trouble Diagnose

The KHR2433 is a passive thermistor, so the controller reports faults as open-circuit, short-circuit, or out-of-range temperature codes rather than a single “KHR2433 code.” The exact DTC numbering varies by platform.

1. 7041 Oil temperature sensor — open circuit Resistance ≥ 67,200 Ω (signal voltage ≥ 4.93 V) detected after engine start; indicates an open sensor element or broken harness
2. 7041 (short-circuit side) Oil temperature sensor — short circuit Resistance ≤ 111 Ω; indicates a short to ground or a failed sensor
3. 7005 Hydraulic oil temperature sensor circuit malfunction ECM detects an abnormal voltage signal from the hydraulic oil temperature sensor
4. 7210 Hydraulic oil temperature sensor circuit malfunction / abnormal signal ECM detects an abnormal signal from the hydraulic oil temperature sensor circuit
