Component Testing

TP Sensor

  1. Ignition OFF, disconnect the harness connector of the throttle body assembly.
  2. Measure for 1,160-1,175 ohms between the 5-volt reference and the low reference terminals of the TP sensor.
    • If the resistance is not within the specified range, replace the TP sensor.
  3. Measure the resistance between the signal terminal and the low reference terminal of the TP sensor. Sweep the TP sensor through the entire range. The resistance should vary between 1,530 and 630 ohms without any spikes or dropouts.
    • If the resistance is not within the specified range or is erratic, replace the TP sensor.
  4. Apply 5-volts and ground to the applicable terminals of the TP sensor, and measure the voltage between the signal and the low reference terminals. Sweep the TP sensor through the entire range. The voltage should vary between 4.3-0.6 volts without any spikes or dropouts.
    • If the voltage is not within the specified range or is erratic, replace the TP sensor.

MAP Sensor Skewed Signal Test

  1. Ignition OFF, remove the vacuum source from the MAP sensor.
  2. Ignition ON, observe and record the scan tool MAP sensor pressure data parameter. This is the first MAP sensor reading.
  3. With the J 23738-A apply 5 in Hg (17 kPa) of vacuum to the MAP sensor. Observe and record the scan tool MAP sensor pressure data parameter. This is the second MAP sensor reading.
  4. Subtract the second MAP sensor reading from the first MAP sensor reading. Verify that the vacuum decrease is within 1 in Hg (4 kPa) of the applied vacuum.
    • If the vacuum decrease is not within the specified range, replace the MAP sensor.
  5. With the J 23738-A apply 10 in Hg (34 kPa) of vacuum to the MAP sensor. Observe and record the scan tool MAP sensor pressure data parameter. This is the third MAP sensor reading.
  6. Subtract the third MAP sensor reading from the first MAP sensor reading. Verify that the vacuum decrease is within 1 in Hg (4 kPa) of the applied vacuum.
    • If the vacuum is not with in the specified range, replace the MAP sensor.

MAP Sensor Skewed Signal Test

  1. Ignition OFF, remove the vacuum source from the MAP sensor.
  2. Install a 3A fused jumper wire between the 5-volt reference circuit terminal C and the corresponding terminal of the MAP sensor.
  3. Install a jumper wire between the low reference circuit terminal A of the MAP sensor and ground.
  4. Install a jumper wire at terminal B of the MAP sensor.
  5. Connect a DMM between the jumper wire from terminal B of the MAP sensor and ground.
  6. Ignition ON, install the J 23738-A to the MAP sensor vacuum port. Slowly apply vacuum to the sensor while observing the voltage on the DMM. The voltage should vary between 0.0-5.2 volts, without any spikes or dropouts.
    • If the voltage reading is erratic, replace the MAP sensor.
