Intake Manifold Temperature Sensor Voltage Out of Range
Intake manifold temperature sensor voltage signal is out of the expected range.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The intake manifold temperature sensor is supposed to send a voltage signal to the engine control unit (ECU) that indicates the temperature of the air inside the manifold. If the voltage is too high or too low, it means the sensor is malfunctioning or has a bad connection.
What the computer is actually seeing
The ECU expects a voltage signal from the intake manifold temperature sensor typically between 0.5V (low temp) and 4.5V (high temp). If the voltage is above 4.5V or below 0.5V, the ECU triggers this fault code.
What a healthy reading looks like
Intake manifold temperature should read between 10°C (50°F) and 80°C (176°F) under normal operating conditions.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Check the wiring and connectors to the intake manifold temperature sensor for frays, burns, or disconnections.
- 22. Using a multimeter, measure the voltage at the sensor connector with the engine running. Is it between 0.5V and 4.5V? If yes, the sensor or wiring is likely good; if no, continue to step 3.
- 33. Disconnect the sensor and measure the resistance. Is the resistance within spec? (Refer to manufacturer service specifications for exact values.) If yes, replace the sensor; if no, inspect wiring for shorts/open circuits.
Common causes
- Faulty intake manifold temperature sensor
- Wiring issues or bad connectors
- Short circuit in the sensor circuit
- Open circuit in the sensor circuit
