P0110 - Intake Air Temperature (IAT) Sensor Circuit
The Intake Air Temperature (IAT) sensor resistance changes in response to the intake air temperature. The sensor resistance decreases as the surrounding air temperature increases. This provides a signal to the PCM, indicating the temperature of the incoming air charge.
The following symptoms can be caused by a faulty IAT sensor due to loose connections, bad grounds, high resistance in the circuit, or opens in the circuit.
P0170 - Fuel Trim Bank 1
Possible Causes
- Intake air leaks
- Front Heated oxygen sensor may be faulty
- Injectors may be faulty
- Exhaust gas leaks
- Incorrect fuel pressure
- Lack of fuel
- Mass air flow sensor may be faulty
- Incorrect PCV hose connection
So the answer is YES, they can be related. Possible Causes of P0170 - Intake air leaks also if there is a leak, this may also mean that is might be affecting P0110 as it can't give correct readings
But hey, I'm no guru
