The Northstar engine uses two O2 sensors. Sensor 1 is located on a bung in the exhaust after the manifold, but before the catalytic convertor. Sensor 2 is located after the catalytic convertor. It's that simple.

The O2 sensor on a 2003 Cadillac Northstar engine is located in the exhaust manifold. The readings from this sensor are sent to the vehicle's computer, which makes constant adjustments to the fuel and air mixture.

The 1983 Cadillac Deville oil pressure sensor can be found on the side of the engine. The oil pressure sensor will be on the left-hand side of the engine.

There is no camshaft sensor But the crankshaft sensor is above the Oil filter adaptor I bought one of these cars, very poor decision on my part. BEWARE of any northstar with over 80K on it.
