RESISTANCE TEST

(1) Disconnect connector P72 from transmission

engine speed sensor.

(2) Set multimeter to ohms.

(3) Connect positive (+) probe of multimeter to

pin A of transmission engine speed sensor.

NOTE

A good transmission engine speed sensor

will return a reading of 200-400 ohms

resistance as follows:

a. 200 ohms at

- 40° F (- 40° C)

b. 300 ohms at

68° F (20° C)

c. 400 0ohms at

230° F (110° C)

(4) Connect negative (-) probe of multimeter to

pin B of transmission engine speed sensor

and note reading on multimeter.

(5) If good resistance is not noted, replace

transmission engine speed sensor

(para 7-52).

(6) Connect connector P72 to transmission

engine speed sensor.

NOTE

Use care when testing electrical connectors.

Do not damage connector pins or sockets

with multimeter probes.

Failure to comply

may result in damage to equipment.

Loose or dirty connectors may cause

intermittent loss of power to transmission

ECU and diagnostic codes to be logged.

Ensure that all connectors are clean and tight

before performing troubleshooting.

Failure to

comply may result in incorrect test results.

CAUTION

Wear appropriate eye protection when

working under vehicle due to the possibility

of falling debris.

Failure to comply may

result in injury to personel.

WARNING

Inspect connector pins/sockets for damage,

corrosion, and serviceability.

Check that

connector pins are not pushed back and

are capable of making good contact.
