DRIVE GP-FINAL 5253672 - Caterpillar

The Electronic Control Module (ECM) has been powered for at least five seconds. The signal from the inlet air temperature sensor to the ECM is greater than 4.8 VDC for at least five seconds. Additionally, neither of the following diagnostic codes are active:
262 - 03 5 Volt Sensor DC Power Supply short to +batt
262 -04 5 Volt Sensor DC Power Supply short to groundSystem Response:The ECM assumes the last valid value for the inlet air temperature. The monitoring of the inlet air temperature is disabled. This disables the engine protection for high inlet air temperature. The air/fuel ratio control cannot compensate for the inlet air temperature.The fuel is shut off. The shutdown output is activated. The code is logged.Possible Performance Effect:The engine is shut down.Troubleshooting:The condition indicates a possible open circuit or a short circuit to a positive voltage source.Test Step 1. Perform the following diagnostic procedure: "Analog Sensor Signal"Results:
OK - STOP
