DME 7.8 DME 7.8 0 0-15P0115 123 Engine temperature - signal implausible Diagnosis conditions • A temperature model is formed. If the measured temperature deviates too much from the calculated temperature, a fault is detected. Note! A thermostat which is constantly open can cause the fault P0115. Possible fault cause ♦Thermostat (permanently open) ♦Open coolant shutoff valve (only Tiptronic vehicles) ♦Wiring ♦Temperature sensor faulty ♦DME control module faulty Affected terminals Terminal III/22 and III/17 Resistance values 0 °C 5.0 - 7.0 kΩ 20 °C 2.0 - 3.0 kΩ 60 °C 0.4 - 0.8 kΩ Diagnosis/troubleshooting Work instruction Display OK If not OK 1 Check thermostat ⇒ Step 2 Replace thermostat → End 2 Check coolant shutoff valve in Tiptronic vehicles ⇒ Step 3 Replace coolant shutoff valve in Tip- tronic vehicles → End 2462 P0115 0-15 page 1 Printed in Germany, 2000 p0115
