Issue with o2 sensor and map sensor, when disconnected no fault codes are flashed, the sensors are working as they effect the engine running condition. o2 sensor output OK.
If I disconnect tps or water temp or air temp sensors the codes will appear. Just wonder if there is a fault within the ecm not detecting a disconnect.

My MAP DTC won't set due to low voltage unless the throttle is held open past 5°.
