You add washer fluid or fix the fluid sensor.
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.
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. = )
On my 94, I6, it was lower right, from the front of the vehicle. There is a wire from the distributor to the sensor. Follow that.
It is bolted to the transmission bell housing, drivers side, near the top. The bolts advance toward the front of the vehicle. It is nested in a rubber boot and senses teeth on the flywheel to detect top dead center and 180 degrees off TDC.
The 1997 Chevy 1500 throttle position sensor is located on the firewall in the engine compartment. The throttle position sensor will be in the center of the firewall.
The vehicle speed sensor is located on the top center of the rear axle.
The alarm box controls the shutdown of the vehicle when it gets too hot by using information from a temperature sensor. The CDI will shut down. It also controls the red warning light.
The ABS and brake warning lights will come on in a vehicle when an error is detecting in the he system. This can range from low fluid or pressure to sensor and component failure.
Top center of the rear axle.
Based on the information given in the question, I can think of three possibilities: -- The vehicle is moving at an excessive rate of speed. -- The speed sensor is defective. -- Something else is broke.
To help you turn your backup sensor on I would need more information. What does the backup sensor go on? What type of vehicle? What year is it? an what model vehicle is it?
There is no vehicle speed sensor wire. The transmission computer calculates vehicle speed from its output speed sensor and sends that information on the communication wires to the cluster.
The DPFE sensor is located in the center of the vehicle near the firewall. It is easiest to see and replace if you remove the plastic cover on top of the engine.
Turning off the airbag warning light on a vehicle is unsafe. The light is on for a reason, either a bad sensor, or an issue with the airbag. Either way, you should bring this in to a mechanic to have it looked at.
Sounds like the switch/sensor is bad. Often the guage sensor and warning light sensor are different.
The vehicle speed sensor is the sensor on top of the rear axle. If the vehicle has 4 wheel ABS then there will be a speed sensor on each front wheel.
The "upstream" sensor on the 6cyl is on the exhaust pipe just after the head. You can see it just to the right of "center" as engine is sideways in vehicle. The "downstream" sensor can be seen on the passenger side of the vehicle just after the catalytic converter. The sensor points out to the right side of the vehicle. There is a grommet the attaches to the underbody of the vehicle. Some say that the passenger seat can be removed and an access plate provides access to the sensor. But, the sensor is visible and accessible from under the vehicle. The grommet to the end of the wire lead with connector is about 10 inches and may be housed inside the body.
