Released in 2000, the Pontiac Grand Am was the company’s mainstream midsize car offering. It featured an optional 3.4-liter V6 engine, which could produce up to 170 horsepower. To keep the engine running in top condition, the Grand Am is equipped with a throttle position sensor (TPS). This component ensures the fuel and air mixture entering the engine is precisely calibrated for optimal performance. The TPS is monitored by the onboard computer and connected to the engine by a wiring harness.
If you own a 2000 Pontiac Grand Am and are looking for a wiring diagram for your vehicle’s TPS, here’s what you need to know. The Grand Am’s TPS is wired into the car’s electrical system via a six pin connector. The connector’s terminals are designated from 1 to 6 and the wiring harness is color-coded. Terminal 1 is orange, terminal 2 is purple, terminal 3 is white, terminal 4 is blue, terminal 5 is black and terminal 6 is green.
Knowing the wiring diagram of your car’s TPS can be incredibly helpful when troubleshooting electrical problems or replacing the part. It’s also important to make sure that each wire is properly connected to the correct terminal otherwise the engine may not run correctly or experience significant power loss. If you’re unsure about how to identify the wires on your 2000 Pontiac Grand Am TPS, consult a licensed mechanic or auto electrician. They will be able to map out the wiring diagram for you and ensure the car’s TPS is properly connected.
