What Is P1193 Code on Dodge Cummins? (How to Fix It)
The Inlet Air Temperature (IAT) Sensor is a two-wire thermistor that decreases thermistor resistance and signal voltage when the intake air temperature rises.
In the Powertrain Control Module, electricity is routed over a high resistance circuit while the engine is cold (PCM).
In the PCM, electricity is transmitted over a low resistance circuit while the engine is warm.
The PCM dual circuit enhances IAT accuracy over the whole temperature range. For fuel calculations, PCM monitors IAT voltage to assist in determining air density owing to temperature.
When the engine is operating, the circuit is monitored.
When the Inlet Air Temperature (IAT) sensor voltage exceeds 4.9 volts, a Diagnostic Trouble Code (DTC) is set.
The following is a quick explanation and definition of the P1193 code.
What Does P1193 Code Mean on Dodge Cummins?
This is a common powertrain diagnostic trouble code (DTC) seen in most OBD-II vehicles.
Dodge Ram (Cummins), GMC Chevrolet (Duramax), Volkswagen, Audi, Ford (Powerstroke), Mercedes Sprinter, Peugeot, Alfa Romeo, Nissan, Saab, Mitsubishi, and other vehicles may be impacted.
Although the methods are straightforward, they may vary depending on the year, make, model, and powertrain configuration.
Temperature circuits are an important part of the gasoline distribution system in today’s autos.
Symptoms of Getting the P1193 Code on a Dodge Cummins
There are a few clues that this response will occur:
The first is that the check engine light illuminates.
The second issue is that the automobile does not accelerate when the gas pedal is pressed.
Another indicator is when the engine stalls when the accelerator is pressed. You may notice a few additional signs when identifying the problem. The first is a decrease in the efficiency of gas mileage.
Another symptom that the engine isn’t getting what it needs is low gas pressure.
You may hear rattling noises coming from the back of the car when the part breaks. An illuminated engine light or a service engine soon warning light might be a sign.
During cold starts, engine power is less than usual.
Instabilities during idle.
The Causing Factors of the Error Code P1193
The several causing factors of the P1193 code is given below:
- Faulty Inlet Air Temperature (IAT) Sensor
- Inlet Air Temperature Sensor harness is open or shorted
- Inlet Air Temperature Sensor Circuit poor electrical connection
- Faulty Powertrain Control Module (PCM)
How Serious Is Code P1193 on Dodge Cummins?
A substantial failure in the inlet air temperature sensor voltage supply circuit causes code P1193, which causes the malfunction to the sensor to perform smoothly.
Repairing the control modules might be costly. These critical modules are required for the air system to work correctly.
How to Solve P1193 Error Code on Dodge Cummins?
A substantial failure in the fuel injector voltage supply circuit causes code P1193, which causes the engine to run rough and misfire.
The steps to solve this problem are given below:
- Consult the Technical Service Bulletins for further information.
- Examine the IAT Sensor’s wire for burns or damage, and make sure it’s in good working order. If you discover the aforementioned issues, make the necessary repairs or adjustments.
- Examines and monitors the voltages of the Intake Air Temperature Sensor circuit connections. These readings must fall within the manufacturer’s standards.
- Make the necessary repairs if you discover a voltage that is out of range.
- Check the Intake Air Temperature Sensor’s resistance to see if it’s within the guidelines for optimum sensor operation. Otherwise, you’ll have to get a new one.
How Much Does It Cost to Solve the Error Code P1193?
The labor cost to diagnose the P1193 DODGE code is 1.0 hours.
The diagnosis time and labor prices for auto repairs vary by region, vehicle make and model, and even engine type.
The average hourly rate at an auto repair shop is $75 to $150.
Employing a dealership to fix your vehicle will, of course, be more expensive than hiring an individual mechanic. Unless you have substantial automotive repair expertise, you should not attempt replacement yourself in most cases.
Common Mistakes While Solving the P1193 Code
P1193 Engine speed is less than 470 RPM.
Various causes components might be contributing to this drivability problem.
THROTTLE SYSTEM IN ELECTRONIC MODE (ETS). In the majority of circumstances, an ETS-related DTC will generate two codes.
The first code identifies the system or component in question.
The second code is for the specific fault detected.
P1191 was most likely present as well.
Additional Comments to Consider Regarding the P1193 Code
There is almost certainly a problem with the fuel pump when the issue numbers show. This might be a costly solution. There are a few things you should do to keep your gasoline pump in good operating order.
To begin, use only high-quality fuel. The fuel pump wears down when you use low-quality gasoline because it has to filter a lot of contaminants.
As a result, always follow your vehicle’s manufacturer’s fuel recommendations. Then you should never drive on a low fuel tank or let your car get close to running out of petrol.
Contaminants build up and clog the component when the automobile is running on low gas. The fuel pump will ultimately break out.
The lifters are unable to elevate their partner push rods beneath the valve rocker arms in their compressed position, resulting in valves that cannot be activated and remain closed.
The failure might be the ECM or a separate injector driver module on some autos, and code P1193 is for diesel and some gas engines.
Conclusion
I hope our discussion today gave you all of the knowledge you needed. It was over when it comes to the P1193 code on a Dodge Cummins.
Keep an eye on the code and attempt to fix it as soon as possible. Take into account all of my suggestions and, if required, seek professional aid.
