Sub-steps:
1. Locate the oil pressure sending unit (usually near the oil filter).
2. Disconnect the electrical connector from the sending unit.
3. Remove the sending unit using a socket or wrench.
4. Install the new sending unit and torque it to specifications.
5. Reconnect the electrical connector.

4. Inspect and Replace Oil Pump (if necessary)

Sub-steps:
1. Drain the engine oil again.
2. Remove the oil pan by unbolting it (ensure to check for any mounting bolts).
3. Remove the old oil pump (may require removing timing belt or chain, consult service manual).
4. Install the new oil pump and torque bolts to specifications.
5. Reinstall the oil pan with a new gasket and torque to specifications.
