Where is Jeep Grand Cherokee Laredo outside temperature sensor. Temp always reads 0C. will sensor replacement fix this?
The Ambient air temperature is monitored by the Electronic Vehicle Information Center (EVIC) through ambient temperature messages received from the Body Control Module (BCM) over the Programmable Communications Interface (PCI) data bus network. The BCM receives a hard wired input from the ambient temperature sensor. The ambient temperature sensor is a variable resistor mounted to a bracket that is secured with a screw to the right side of the headlamp mounting module grille opening, behind the radiator grille and in front of the engine compartment. The ambient temperature sensor cannot be adjusted or repaired and, if faulty or damaged, it must be replaced.OPERATIONThe ambient temperature sensor is a variable resistor that operates on a five-volt reference signal sent to it by the BCM. The resistance in the sensor changes as temperature changes, changing the temperature sensor signal circuit voltage to the BCM. Based upon the resistance in the sensor, the BCM senses a specific voltage on the temperature sensor signal circuit, which it is programmed to correspond to a specific temperature. The BCM then sends the proper ambient temperature messages to the EVIC over the PCI data bus.The temperature function is supported by the ambient temperature sensor, a wiring circuit, the Body Control Module (BCM), the Programmable Communications Interface (PCI) data bus, and a portion of the Electronic Vehicle Information Center (EVIC) module. If any portion of the ambient temperature sensor circuit fails, the BCM will self-diagnose the circuit. A temperature reading of 130° F will appear in the EVIC display in place of the temperature when the sensor circuit is shorted. A temperature reading of -40° F will appear in the EVIC display in place of the temperature when the sensor circuit is open.
Should a Jeep Cherokee bad oxygen sensor be changed when the vehicle runs great with the light on or off?
It depends on whether you are in a state that requires Smog certification, and also by what you consider 'runs great'. A faulty Oxygen Sensor will never pass a Smog check, so if one is required to register the vehicle, you have no choice. Just because a vehicle seems to 'run great', doesn't mean that it actually is. I would suggest replacing the sensor as soon as your finances will allow. That sensor is an integral part of the emission system, and the emission system an integral part of the overall performance of the vehicle. Garbage in, garbage out my friend. = )

How do you replace 240 dl bulb failure warning sensor?
To replace a 240 dl bulb failure warning sensor, first disconnect the vehicle's battery to ensure safety. Locate the sensor, typically found near the rear light assembly or in the vehicle's fuse box. Remove the old sensor by disconnecting its wiring harness and unscrewing it if necessary, then replace it with the new sensor and reconnect the wiring. Finally, restore power by reconnecting the battery and test the system to ensure the warning light is no longer illuminated.
