Toyota Corolla (E120): Overhaul
1. Remove oil pump relief valve
- Remove the oil pump relief valve plug, oil pump relief valve spring and oil pump relief valve.
- Oil pump relief valve plug
- oil pump relief valve spring
- oil pump relief valve
2. Inspect oil pump assy
- Remove 3 screws and oil pump cover.
- Inspect the oil pump relief valve.
- Coat the valve with engine oil and check that it falls smoothly into the valve hole by it own weight.
- inspect the oil pump rotor sub–assembly.
- Coat the oil pump gear set with engine oil and place them into the oil pump body. Check that the rotors revolves smoothly.
- inspect rotor tip clearance.
- Using a feeler gauge, measure the clearance between
the drive and driven rotor tips.
Standard tip clearance: 0.040 – 0.160 Mm (0.0016 – 0.0063 In.)
- Inspect body clearance.
- Using a feeler gauge, measure the clearance between
the driven rotor and body.
Standard body clearance: 0.260 – 0.325 Mm (0.0102 – 0.0128 In.)
- Inspect rotor side clearance.
- Using a feeler gauge and precision straight edge,
measure the clearance between the rotors and precision
straight edge.
Standard side clearance: 0.025 – 0.071 Mm (0.0010 – 0.0028 In.)
- Install oil pump rotor sub–assembly.
- Coat the oil pump gear set with engine oil and place it into pump body with the marks facing the pump body cover side.
- Install oil pump rotor sub–assembly.

Inspection procedure
Hint:
if different dtcs related to different systems that have terminal e2
as the ground terminal are output
simultaneously, terminal e2 may be open.

Eco drive mode (if equipped)
Press the switch.
Suitable for enhancing the fuel economy, because the torque corresponding to
the accelerator pedal depression amount can be generated more smoothly than it is
in normal conditions and the operation of the air conditioning system (heating/cooling)
will be minimized.
