How many different sensors are on a Chrysler PT Cruiser engine?

There's no single definitive answer to how many sensors are on a Chrysler PT Cruiser engine. The exact number varies depending on the year of manufacture, the specific engine (2.4L, 2.2L, etc.), and even the options package of the vehicle.

A PT Cruiser engine will have numerous sensors, likely ranging from 15 to 25 or more. These include, but aren't limited to:

* Crankshaft Position Sensor (CKP): Essential for engine timing.

* Camshaft Position Sensor (CMP): Also crucial for engine timing.

* Mass Airflow Sensor (MAF): Measures the amount of air entering the engine.

* Throttle Position Sensor (TPS): Monitors throttle plate position.

* Oxygen Sensors (O2): One or more, monitoring exhaust gas composition.

* Manifold Absolute Pressure (MAP) Sensor: Measures intake manifold pressure.

* Coolant Temperature Sensor (CTS): Monitors engine coolant temperature.

* Air Temperature Sensor (IAT): Measures intake air temperature.

* Knock Sensors: Detect engine knock (pre-ignition).

* Brake Switch: Provides input to the engine control module (ECM).

* Various other sensors related to emissions, transmission, and other systems that may indirectly impact the engine.

To find the exact number for a specific PT Cruiser, you would need to consult a repair manual or parts diagram for that particular year and engine.
