w/o AVS | A |
w/ AVS | B |
B | GO TO STEP 5 |
|
2. | CHECK HARNESS AND CONNECTOR (SENSOR GROUND CIRCUIT) |
(a) Make sure that there is no looseness at the locking part and the connecting part of the connectors. OK: The connector is securely connected. |
|
(b) Disconnect the A92 front speed sensor LH connector.
(c) Check both the connector case and the terminals for deformation and corrosion.
OK:
No deformation or corrosion.
(d) Turn the engine switch on (IG).
(e) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
Tester Connection | Condition | Specified Condition |
---|---|---|
A92-3 (FL+) - A92-4 (FL-) | Engine switch on (IG) | 11 to 14 V |
OK | REPLACE FRONT SPEED SENSOR LH |
|
3. | CHECK HARNESS AND CONNECTOR (SENSOR GROUND CIRCUIT) |
