List of Common automotive Sensors

The electronic engine controls consist of the following:

  • – PCM
  • – Throttle Position (TP) sensor
  • – Idle Air Control (IAC) valve
  • – Engine Coolant Temperature (ECT) sensor (4.0L)
  • – Camshaft Position (CMP) sensor
  • – Crankshaft Position (CKP) sensor
  • – Mass Air Flow (MAF) sensor
  • – Manifold Absolute Pressure (MAP) sensor (2.3L)
  • – Intake Air Temperature (IAT) sensor
  • – Heated Oxygen Sensor (HO2S)
  • – Catalyst Monitor Sensor (CMS)
  • – Wheel speed sensor
  • – Cylinder Head Temperature (CHT) sensor (2.3L)

The PCM:

– accepts input from various engine sensors to compute the fuel flow rate necessary to maintain a prescribed air/fuel ratio throughout the entire engine operating range.
– outputs a command to the fuel injectors to meter the appropriate quantity of fuel.
The TP sensor:

– sends the PCM a signal indicating the throttle plate angle.
– is the main input to the PCM from the driver.

The IAC valve:

– controls bypass air around the throttle plate at low speeds.
– is controlled by the PCM.

The ECT sensor (4.0L):

– sends the PCM a signal indicating engine coolant temperature.
– resistance decreases as coolant temperature increases.

The CHT sensor (2.3L):

– sends the PCM a signal indicating cylinder head temperature.

The CMP sensor:

– provides camshaft position information which is used by the PCM for fuel synchronization.

The CKP sensor:

– sends the PCM a signal indicating crankshaft position.
– is essential for calculating spark timing.

The MAF sensor:

– uses a hot wire sensing element to measure the amount of air entering the engine.
– sends the PCM a signal to determine the intake air mass. The PCM will then calculate the required fuel injector pulse width in order to provide the desired air/fuel ratio.

The MAP sensor:

– measures manifold vacuum and converts it to an electrical signal. This provides the PCM information on engine load.

The IAT sensor (4.0L):

– sends the PCM a signal indicating the temperature of the air entering the engine.
– resistance decreases as temperature increases.

The HO2S:

– has the ability to create a voltage signal dependent on exhaust oxygen content.
– provides feedback information to the PCM used to calculate fuel delivery.

The CMS:

– has the ability to create a voltage signal dependent on exhaust oxygen content.
– provides feedback information to the PCM used to calculate fuel delivery.

The wheel speed sensor:

– sends a signal to the PCM indicating wheel speed.
