Why would OBD codes p0113 p0118 and p1607 all appear together?

OBD codes P0113 (Intake Air Temperature Sensor Circuit High), P0118 (Engine Coolant Temperature Sensor Circuit High), and P1607 (ECM/PCM Internal Temperature Sensor Performance) may appear together due to issues related to the vehicle's temperature sensor circuit or electrical system. A common cause could be a faulty wiring harness, poor connections, or a failing engine control module (ECM) affecting multiple sensors. Additionally, a significant electrical problem, such as a short circuit or ground issue, could lead to erroneous readings across these sensors. It's essential to diagnose the root cause to address the problem effectively.
