Honda P1106 Code is a diagnostic trouble code (DTC) that is triggered when the powertrain control module (PCM) detects a performance issue with the barometric pressure sensor. This code is set when the PCM detects that the barometric pressure sensor input did not change within a specified period of time while the engine was running in 4th gear and then accelerated to wide open throttle (WOT). In order to ensure the proper functioning of the vehicle, it is important to understand the potential causes and solutions to this code. In this article, we will be exploring the causes and solutions to the Honda P1106 Code.
Causes and Solutions to Honda P1106 Code
| Cause | Solution |
|---|---|
| BARO sensor signal circuit is open or shorted to ground | Check the wiring for any signs of damage or corrosion, and if necessary, replace any damaged wiring. |
| BARO sensor ground circuit has high resistance | Check the ground circuit for any signs of damage or corrosion and replace the ground circuit if necessary. |
| BARO sensor is damaged or out of calibration | Check the BARO sensor for any signs of damage or wear and tear, and if necessary, replace the BARO sensor. |
| PCM has failed | Replace the PCM if necessary. |
When a Honda vehicle displays the P1106 Code, it indicates that the powertrain control module has detected a performance issue with the barometric pressure sensor. This code is set when the PCM detects that the barometric pressure sensor input did not change within a specified period of time while the engine was running in 4th gear and then accelerated to wide open throttle (WOT). There are several potential causes for this code, and it is important to understand them in order to properly diagnose and fix the issue. Potential causes include an open or shorted BARO sensor signal circuit, a high resistance BARO sensor ground circuit, a damaged or out of calibration BARO sensor, and a failed PCM. In order to properly diagnose and fix the issue, it is important to understand the potential causes and solutions to the Honda P1106 Code.
BARO Sensor Signal Circuit
The first potential cause of the Honda P1106 Code is an open or shorted BARO sensor signal circuit. This means that the wiring running from the BARO sensor to the PCM is either open or shorted to ground. In this case, it is important to check the wiring for any signs of damage or corrosion, and if necessary, replace any damaged wiring.
BARO Sensor Ground Circuit
The second potential cause of the Honda P1106 Code is a high resistance BARO sensor ground circuit. This means that the ground wire running from the BARO sensor to the PCM is experiencing a high amount of resistance. In this case, it is important to check the ground circuit for any signs of damage or corrosion and replace the ground circuit if necessary.
BARO Sensor
The third potential cause of the Honda P1106 Code is a damaged or out of calibration BARO sensor. This means that the BARO sensor itself is either damaged or out of calibration, and is not providing an accurate reading to the PCM. In this case, it is important to check the BARO sensor for any signs of damage or wear and tear, and if necessary, replace the BARO sensor.
PCM
The last potential cause of the Honda P1106 Code is a failed PCM. This means that the powertrain control module itself has failed and is not providing an accurate reading to the PCM. In this case, it is important to replace the PCM if necessary.
Conclusion
The Honda P1106 Code is an important diagnostic trouble code that is triggered when the powertrain control module detects a performance issue with the barometric pressure sensor. In order to ensure the proper functioning of the vehicle, it is important to understand the potential causes and solutions to this code. This article has outlined the potential causes and solutions to the Honda P1106 Code which include an open or shorted BARO sensor signal circuit, a high resistance BARO sensor ground circuit, a damaged or out of calibration BARO sensor, and a failed PCM. By understanding the potential causes and solutions to the Honda P1106 Code, it is possible to properly diagnose and fix the issue.
