939005199 - Y075 P2080 - TEMPERATURE SENSOR ON CATALYTIC PRECONVERTOR OUTLET

The diagnostic equipment signals: Error P2081 (temp. sensor at catalytic preconverter outlet).

This error is detected if voltage at Pin 34 of the electronic control module is greater than 2.23 V (short circuit to positive) (detail "short circuit to +Vbatt or open circuit") or less than 0.66 V (short circuit to earth or break in the circuit) (detail "short circuit to earth"). The control unit takes 200 °C as the replacement value.
