Nope. The computer doesn't even look at the oxygen sensor until the oxygen sensor reaches operating temperature.
An oxygen sensor is a device that measures the oxygen in a car's exhaust. The computer uses this to adjust the amount and timing of fuel injected.
The MAP sensor on a Trailblazer is the Manifold Air Positioning sensor. It is located on the top of the engine.
The computer uses the oxygen sensor reading from the exhaust to adjust the amount of fuel injected into the engine.
Not directly. The oxygen sensor measures oxygen levels in the exhaust. The computer uses that to calculate fuel and spark timing. If an oxygen sensor is malfunctioning, it could cause idle problems.Not directly. The oxygen sensor measures oxygen levels in the exhaust. The computer uses that to calculate fuel and spark timing.
