Toyota Camry (XV70): Inspection
INSPECTION
PROCEDURE
1. INSPECT OIL PUMP RELIEF VALVE
| (a) Coat the oil pump relief valve with engine oil and check that it falls smoothly into the valve hole by its own weight. HINT: If the oil pump relief valve does not fall smoothly, replace the timing chain cover assembly. |
|
2. INSPECT OIL PUMP ROTOR SET
(a) Apply engine oil to the drive rotor and driven rotor.
| (b) Install the drive rotor and driven rotor to the timing chain cover assembly with the rotor marks facing up. Check that the rotors rotate smoothly. HINT: If the rotors do not rotate smoothly, replace the timing chain cover assembly. |
|
| (c) Check the tip clearance. (1) Using a feeler gauge, measure the clearance between the drive rotor and driven rotor tips as shown in the illustration. Standard Tip Clearance: 0.040 to 0.150 mm (0.00157 to 0.00591 in.) Maximum Tip Clearance: 0.150 mm (0.00591 in.) HINT: If the tip clearance is more than the maximum, replace the timing chain cover assembly. |
|
| (d) Check the side clearance. (1) Using a feeler gauge and precision straightedge, measure the clearance between the drive rotor and driven rotor and precision straightedge as shown in the illustration. Standard Side Clearance: 0.030 to 0.070 mm (0.00118 to 0.00276 in.) Maximum Side Clearance: 0.070 mm (0.00276 in.) HINT: If the side clearance is more than the maximum, replace the timing chain cover assembly. |
|
| (e) Check the body clearance. (1) Using a feeler gauge, measure the clearance between the timing chain cover assembly and driven rotor as shown in the illustration. Standard Body Clearance: 0.250 to 0.325 mm (0.00984 to 0.0128 in.) Maximum Body Clearance: 0.325 mm (0.0128 in.) HINT: If the body clearance is more than the maximum, replace the timing chain cover assembly. |

VC Output Circuit
DESCRIPTION The ECM constantly generates a 5 V power source voltage from the battery voltage supplied to the +B, +B2 (BATT) terminals to operate the microprocessor. The ECM also provides this power to the sensors through the VC output circuit.
When the VC circuit has a short circuit, the micropro
