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.

I get a 1 then a 4 then a 23 then it goes to 55 what do these three codes mean the 23 in book says air intake sensor voltage it's on a 1999 3.3 caravan but can't find these three codes what do

Preaty problem you got there but how did u got those codes if it is a 99 you should get a generic obd II code that start with the letter P but try from the basic inspect your plugs and wires and if are those are okay you could have a bad cranck possition sensor but I will suggest you to get a OBD II scaner to see if you can get a generic code

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.

Honda prelude code 16 trans and 23

I took a look around online & found a website.
Per site says Code 16 is a Fuel Injector & 23 is a Knock Sensor.

These codes and page references pertain to the Helm Service Manual. You can obtain a helm manual from Helm Inc.
