INSPECTION
PROCEDURE
1. INSPECT CAM TIMING OIL CONTROL SOLENOID ASSEMBLY
(a) Check the resistance.
| (1) Measure the resistance according to the value(s) in the table below. Standard Resistance: | Tester Connection | Condition | Specified Condition | | 1 - 2 | 0 °C (32 °F) | 6.3 to 7.3 Ω | | 20 °C (68 °F) | 6.9 to 7.9 Ω | | 40 °C (104 °F) | 7.4 to 8.6 Ω | If the result is not as specified, replace the cam timing oil control solenoid assembly. | .png) | | *a | Component without harness connected (Cam Timing Oil Control Solenoid Assembly) | | |
(b) Stroke Amount Inspection
| (1) Using vernier calipers, measure length (A) and (B) with the shaft of the cam timing oil control solenoid assembly set in the respective positions shown in the illustration. NOTICE: Do not apply auxiliary battery voltage to the terminals of the cam timing oil control solenoid assembly. HINT: If the shaft does not extend under its own weight, extend the shaft with your fingers. | .png) | | *a | Shaft Side Facing Down | | *b | Shaft Side Facing Up | | *c | Shaft | | |
(2) Calculate the stroke amount based on the difference of length (A) and (B).
Standard:
4.3 mm (0.169 in.) or more
HINT:
Stroke amount = length (A) - length (B)
If the value is not as specified, replace the cam timing oil control solenoid assembly.
