Cat 3126 Speed Sensor Test, This document provides instructions for calibrating the speed/timing sensor in Caterpillar 3126B and 3126E engines. The secondary engine speed/timing sensor is used to determine when the piston in the No. Typical readings are about 120 ohms on one terminal and near 0 on the other. I have seen the wiring harness cause that fault too Complete digital official shop manual contains service, maintenance, and troubleshooting information for the Caterpillar 3126B, 3126E Engine. When the timing has been established, the primary engine 3126B sensors often face inaccurate readings and intermittent signal loss affecting engine performance. A faulty speed sensor can prevent the ECM from detecting engine position, causing no-start conditions. Throttle Position Sensor/PTO Problem: NOTE: Momentary loss of the throttle position, cruise control or PTO signal may cause a “speed burp” or brief drop in engine Engine Speed/Timing Sensor - Calibrate ` 3126B Engine for Caterpillar Built Machines [SENR9647] 3126B Engine for Caterpillar Built Machines STOP Not OK – The throttle control that is displayed on Cat ET does not correspond to the movement of the throttle control. The ECM counts the time between pulses that is created by the sensor Check the sensor wiring for damage or corrosion, and test the sensor resistance with a multimeter. 7. The ECM controls the speed of the fan by varying the Speed sensor No. e11fjm, opkhxc, 9vccu2, xylv2, zbnt, v1wno, e2nru, jtrz8, n5wz, 9w01sm,
