2001 Cadillac Deville oxygen sensor wiring diagram

The wiring diagram shows the wiring color code, Power rating and connector plug used. The wiring diagram explains the vehicle's electrical connections with color code. It's a bit complicated to understand.

Where can I find the wiring diagram for this Chevy Colorado 2007 for the Speedometer. I bought this Truck to this local Car Dealer with Speedometer doesn't function at all. I want to try to see what...

Your speedometer is controlled by your computer network. The vehicle speed sensor (VSS) sends a signal to the Body Control Module (BCM) which then relays the speed sensor data via the UART data lines to the Powertrain Control Module (PCM) and the Instrument Panel Cluster (IPC). To find out why your speedometer is not functioning, you must FIRST scan your ENTIRE computer network for possible fault codes. It is possible that either the VSS is defective or the BCM is not able to relay the information due to a communications fault, or the BCM is relaying the information and the IPC is unable to receive the information due to a communications fault, or the IPC itself is defective. Wiring diagrams will be of no use until you determine which parts of the network is receiving the information from the VSS and which parts are not. This will require the use of a scan tool that can not only read generic OBD fault codes, but also access and display codes and live data from the BCM, PCM and IPC.

2002Jeep Liberty speedometer wiring diagram. We are looking for a wiring diagram. The speedometer and cruise control were surging and now they both will cut out plus the overhead console computer no...

wiring from the sensor on the rear diff ? What sensor ? The insturment cluster get's speed info over the PCI bus ( serial data network ) from the PCM - engine computer . The VSS - vehicle speed sensor is located on the transmission . The VSS is a input to the engine computer . Sorry , don't know who told you that . That is not correct . You should have it diagnosed at a qualified repair shop . Your insturment cluster or data network is probably at fault . Does the vehicle shift ok ?
The only sensor that mite be on the rear diff ,could be for the ABS ,an that has nothing to do with the speedometer .
Have the vehicle checked for DTC'S - diagnostic trouble codes .

I need to check Vehicle Speed 1 to sort out a speedo problem, but do not know where the 2 wires lead to. This for a Subaru 1997 Outback

I assume you're referring to the Speed Sensor, and the 2 wires coming from the Speed Sensor? Is your speedometer totally inop, or is it giving improper, or sporadic indications? I'm not familiar with Subaru, but wiring for speed sensors are generally the same for most 96 and newer vehicles. That 2-wire harness typically runs to a disconnect... to the PCM... maybe another disconnect... speedometer. If you have access to schematics, or wiring diagrams, you would need to obtain a few plug and pin numbers, locate the components, then trace a few wires. I'd suggest first running a diagnostic in order to obtain any possible fault codes, and use that as a good starting point.

MAP or MAF Sensor Diagram for 2005 Town&Country Touring Van 3.8l.

Yes it has a sensor and they are color coded however I don't think it's called a maf or map sensor that’s a GM name, there would be three wires on it on ground one 5 volts reference and one for connection to the computer to tell the computer how much air flow there is, and the reading would be from 1.5 volts to 4 volts.
