Top deck sensor fault showing on ecu only when car is warm on a manual 2.0 injection Honda prelude r reg?

A top deck sensor fault in a warm Honda Prelude could indicate an issue with the temperature sensitivity of the sensor or its wiring. It may be related to a faulty sensor, poor connections, or even a problem with the ECU interpreting the signal when the engine reaches operating temperature. It’s advisable to check the sensor’s resistance and wiring for any signs of wear or damage, and consider replacing the sensor if it shows inconsistent readings. Additionally, scanning for any related fault codes can provide further insight into the issue.
