to or over 0.5 of an Ohm of resistance.
4. With the component wire harness connectors disconnected, use a multimeter set to Ohms (Ω), and measure the resistance of the circuit.
5. Use one lead of the meter and probe the circuit in one harness connector.
6. Use the other lead of the meter and probe the same circuit in the other harness connector.
Is the resistance in the circuit below 20k Ohms?
Yes
-
Repair the excessive resistance in the circuit between the two wire harness connectors. Using the wiring application as a guide, trace the circuit and
check for any in-line connectors where the open or excessive resistance could occur.
-
One way to help isolate the open is to disconnect any in-line connectors and measure the resistance from one side of the in-line connector to the
matching component harness connector. If the open or excessive resistance is not present, the open or excessive resistance is on the other side of
the in-line connector
No
-
The circuit does not contain any excessive resistance or the condition that originally caused the excessive resistance may not be present at this
time. Continue to measure the resistance of the circuit, wiggle the wire harness and connectors to check for an intermittent open or poor
connection.
-
Use the wiring application as a guide to trace the circuits and look for any in-line connectors where the open could occur intermittently.
-
Look for any chafed, pierced, pinched, or partially broken wires.
-
Look for broken, bent, pushed out or corroded terminals. Verify that there is good pin to terminal contact in the related wire harness connectors.
-
Perform any Technical Service Bulletins (TSBs) that may apply.
Check The Voltage On A 5-Volt Supply Circuit
CHECK THE VOLTAGE ON A 5-VOLT SUPPLY CIRCUIT
1. MEASURE THE VOLTAGE BETWEEN THE 5-VOLT SUPPLY CIRCUIT AND GROUND
1. Turn the ignition off.
2. Disconnect the sensor harness connector.
NOTE: Check connectors - Clean/repair as necessary.
3. Turn the ignition on.
4. Use a multimeter set to measure DC voltage.
5. Connect the negative lead of the meter to a known good ground.
6. With the positive lead of the meter, carefully probe the 5-volt supply circuit.
Is the voltage between 4.7 and 5.2 volts?
Yes
