Circuit DescriptionThe remote throttle pedal provides the driver’s throttle command to the electronic controlmodule (ECM) through the OEM harness and the original equipment manufacturer’s (OEM)interface harness. The ECM uses this signal to determine the fueling command. Component LocationThe remote throttle pedal location varies with each OEM. Refer to the OEM manual. Shop TalkThe throttle position sensor is a potentiometer. The resistance specifications of the throttleposition sensor is as follows:1) Between supply and return = 2000 to 3000 ohms2) Between supply and signal: Released = 1500 to 3000 ohms; depressed = 200 to 1500 Note: If the throttle or throttle position...

Circuit DescriptionThe oil pressure sensor is used by the electronic control module (ECM) to monitor the lubricating oilpressure. The ECM monitors the voltage on the signal pin and converts this to a pressure value. Theoil pressure value is used by the ECM for the engine protection system. Component LocationThe oil pressure sensor is located on the engine block, below and to the right of the ECM. Shop Talk1) If Fault Code 143 or 415 is not present, the problem is not related to the engine lubricationsystem.2) Your diagnostic tool can be used to monitor the oil pressure signal voltage going...

Circuit DescriptionThe oil pressure switch is used by the electronic control module (ECM) to monitor thelubricating oil pressure. Component LocationThe oil pressure switch is located on the engine block, below and to the right of the ECM. Shop Talk1) If Fault Code 143 or 415 is not present, the problem is not related to the enginelubrication system.2) Your diagnostic tool can be used to monitor the oil pressure signal voltage going into the ECM.3) If an oil pressure switch is installed, INSITE™ will read a constant value of 379 kPa [55psi] ±2 kPa [±0.3 psi] if the ECM is reading...
