Code 23 is the IAT so u have the right sensor i assume, there is only one IAT sensor, it is located in the intake manifold, see picture below, if u are still geeting a code for this it is very poss the connector or the wiring to the sensor has an open circuit.

I have a 1989 fleetwood giving a code 23 which is - 63df7cc.jpg

Keep getting fault codes 12 & 23 on 93 Olds Bravada already replaced Manifold Pressure Sensor and Intake Air Temp Sensor

The code 12 usually just means the system is in diagnostic mode. The code 23 should be for the mat system, not map.

Mat is manifold air temp.
Are there any driveability issues? Does the vehicle start and run ok?

On a cold start i have no high idle for warm up

coolant temp sensor and intake air temp sensor would be the next to check.intake air temp sensor is in the air intake tunnel between TB air air box. when running is there a DTC? by disconnecting the coolant temp sensor you put the ecm values at default try that if it corrects your issue replace it.(it will turn your check engine light on but you can clear later by disconnecting battery)

Symptoms of a bad map sensor on 93 cadillac fleetwood brougham

Well code 23 is a faulty signal from the manifold air temp sensor. The sensor is telling the computer the air temp in the intake is out of range compared to the other readings.
Code 26 is a quad driver problem inside the computer.
Code 34 is a MAP sensor signal saying the vacuum is high when it should be low compared to the other sensors.
They may be connected or separate issues. You could check the MAP with a vac gauge.
I would clear the codes and see which ones come back again.

89 chevy S-10 with 2.5L engine misfiring, when I ran the diagnostic test it showed code 25 or two flashes pause five flashes, what's the problem

Intake air temperature sensor or circuit shorted. Look for sensor popped in on intake hose from air filter. If not connected or wires broken find & repair connection or sensor is bad. Replace.

Car keeps dying

Trouble Code 33 and 34 are the MAF/MAP Sensor Circuit. It sounds like you've replaced that sensor already. Did you also have the code 34 before putting in the new sensor?
Or did this code start after it's replacement? Any other codes appearing?

Troubleshooting it would depend if it has the Speed Density Update. The dealer should be able to provide that info.

Here's your fault code list:

13 oxygen sensor circuit 14 coolant temp sensor circuit (high temp) 15 coolant temp sensor circuit (low temp) 21 throttle position sensor (TPS) circuit (high signal) 22 throttle position sensor (TPS) circuit (low signal) 23 manifold air temp (MAT) circuit (low temp) 24 vehicle speed sensor (VSS) circuit 25 manifold air temp (MAT) circuit (high signal) 31 wastegate solenoid electrical circuit 32 exhaust gas recirculation (EGR) circuit 33 mass air flow (MAF) circuit (gm/sec high) 34 mass air flow (MAF) circuit (gm/sec low) 41 cam sensor circuit 42 C3I EST or bypass circuit failure 43 electronic spark control (ESC) circuit 44 oxygen sensor circuit (lean exhaust) 45 oxygen sensor circuit (rich exhaust) 51 PROM error 52 calpak error 55 ECM error
