Air charge temperture sensor issue

If i connect the air charge temperature sensor the car won't start but if I disconnect it the car works, not very well, but it works.I have changed the sensor but still I get the same symptoms. What could be causing the car to not work when the air charge temperature sensor is connected?

P0111 HYUNDAI - Intake Air Temperature Sensor 1 Circuit Range/Performance Problem.
It is very likely the sensor got disconnected during some service work like replacing the engines air filter.
Other causes- Dirty air filter
- Intake air temperature (IAT) sensor harness is open or shorted
- Intake air temperature (IAT) sensor electrical circuit poor connection
- Faulty intake air temperature sensor

1989 mitsubishi galant, when engine is cold has severe miss, after reaching operating temperature miss disappears, and engine runs smooth.


manifold air temperture or intake air temperture sensor is bad . you can check the voltage on it when cold then w/hair dryer warm sensor up an check voltage if the resistance is more than 500 ohms then it is bad.

What do i do for code 23


Nice Jeep, I have one '93 GC Limited 5.2L V8, monster engine!!!!

About your fault code, this 23 MAT sensor or circuit, and this appears when the air charge temperature sensor signal is out of range - that is, giving a voltage not expected by the computer programmers. The power limited light will come on and the computer will assume that the temperature from the sensor is 70° F. On turbo models, the air charge sensor is located on the intake manifold. On TBI models (fuel injected, no turbocharger) the sensor is referred to as the throttle body temperature sensor and is located on the throttle body.

Possible Reasons for Chrysler Computer Fault Code 23:
- Defective Air Charge Temperature Sensor - The sensor should measure 5,290 ohms to 5,610 ohms at 77 degrees for the 1984 model year. For later models, the measurement should be between 9,120 and 10,880 ohms at 77 degrees.
- Poor wiring or connection - Read the page 'How to troubleshoot drivability issues'. Check the wiring and connections between the sensor and the logic module. Check the harness from the sensor to the computer. Inspect every connector. Clean and re-grease the connectors with dielectric grease. When setting ignition timing it may be necessary to disconnect the sensor from the harness.

Hope helps (remmeber to comment and rate this)

1990 s 10. Test code is 23 ''fuel mixture''. I'm sure it a vacuum problem, however I am not able to correct it. Thanks Dan


fault code 23.Inlet air temperature sensor signal showed an air temperature below -22� F after the engine has been running for 5 minutes,,,,,code 23: MAT low temp indication, sets if the manifold air temperature sensor connections or wires are open for 3 seconds

that being said I'd start by unplugging the wires and make sure the connections are not corroded if so clean them and plug em back in if that does not work try the air charge sensor (the problem when mine had this code) with it acting normal after being shut off and restarted I would lean more toward a corroded or loose connection.

06 pt cruiser dtc p0108,p0113,p0123,and p0508 car will not start


P0108 (M)
Manifold Absolute Pressure/Barometric Pressure Circuit High Input
MAP sensor input above maximum acceptable voltage.

P0113 (M)
Intake Air Temperature Circuit High Input
Intake air (charge) temperature sensor input above the maximum acceptable voltage.


P0508 (M)
Idle Air Control Motor Circuit Low
Idle Air Control Motor Circuit input below acceptable current.

THESE DIFNITIONS ARE FROM THE FACTORY REPAIR MANUAL, LOOKS LIKE YOU MAY HAVE A WIRING HARNESS PROBLEM OR DISCONNECTED COMPONENTS, CHECK THE IAT AND MAP SENSOR AN MAKE SURE THEY ARE CONNECTED.
