How To Test The Output Speed Sensor (1992-1997 2.2L Accord And Odyssey)

Testing The Ignition System (1996, 1997 2.2L Accord EX, Odyssey)

In this tutorial, I'll explain how to test the transmission output speed sensor (also known as the countershaft speed sensor).

The test is done with a multimeter and I'll explain it all in a step-by-step manner and in plain English.

APPLIES TO: This tutorial, on how to test the output speed sensor (countershaft speed sensor), applies to the following vehicles:

  • 2.2L Honda Accord (DX, EX, LX): 1992, 1993, 1994, 1995, 1996, 1997.
  • 2.2L Honda Odyssey: 1995, 1996, 1997.

Location Of The Output Speed Sensor

The transmission output speed sensor (countershaft speed sensor) is located on side of the transmission that faces the rear of the vehicle.

The orange arrow in the photos above point to the output speed sensor.

Testing The Resistance Of The Output Speed Sensor

How To Test The Output Speed Sensor (1995-1997 2.2L Accord And Odyssey)

To find out if the output (countershaft) speed sensor is bad, we're gonna' check its internal resistance with a multimeter in Ohms mode.

The output speed sensor's resistance specification is: 400-600 Ohms.

These are the test steps:

  1. 1

    Disconnect the output speed sensor from its electrical connector.

  2. 2

    Place your multimeter in Ohms mode.

  3. 3

    Measure the resistance across the 2 male terminals of the connector as shown in the illustration above.

  4. 4

    Your multimeter should register a resistance between 400-600 Ohms.

Let's examine your test result:

CASE 1: The resistance was within specification. This is the correct and expectecd test result and it lets you know that the output speed sensor is OK.

CASE 2: The resistance WAS NOT within specification. This test result lets you know that the output speed sensor is bad and needs to be replaced.
