Altitude Sensor
- Disconnect distributor high tension lead from distributor and connect to ground. Remove glove compartment and disconnect main connector from MCU. Disconnect connector terminal from potentiometer.
- Measure resistance between connector pins No. 14 and 18 of the main connector. Resistance should be 2.1-2.6K ohms.
- Measure resistance between connector pins No. 11 and 14. Resistance should be 200-3.6K ohms.
- If resistance is not to specification check wiring continuity. If wires have continuity replace altitude sensor.
