Manifold Pressure/Vacuum Sensor: Testing and Inspection
1985 Renault 18I/Sportwagon L4-2165cc 2.2LSECTION Testing and Inspection
1. Inspect MAP hose and connections at throttle body and sensor. Repair as necessary.
2. With ignition switch On and engine Off, check MAP sensor output voltage at MAP sensor connector terminal B (marked on sensor body). Output voltage should be 4 to 5 volts.
3. Test ECU connector terminal J2-12 for voltage. Voltage should be the same as recorded in step 2. If not, repair wire harness as necessary between sensor and ECU connectors.
4. Check MAP sensor supply voltage at MAP sensor connector terminal C (marked on sensor body). Supply voltage should be 4.5 to 5.5 volts.
5. Test ECU connector terminal J2-2 for voltage. Voltage should be the same as recorded in step 4. If not, repair wire harness as necessary between sensor and ECU connectors.
6. Test MAP sensor ground circuit at MAP sensor connector terminal A (marked on sensor body) and ECU connector terminal J2-13. Repair wire harness as necessary.
7. Test MAP sensor ground circuit again at ECU connector terminals J1-F and J2-13 with an ohmmeter. If an open circuit is indicated, inspect sensor ground connection on flywheel/flexplate housing and repair as necessary. If ground connection is satisfactory, replace ECU. If ECU connector terminal J2-13 indicates 12 volts, repair condition before replacing ECU.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
