P154A Fault Code: Understanding The Description And Troubleshooting Steps
The P154A fault code refers to a problem with the Intake Air Heater (IAH) feedback circuit in the vehicle. The IAH is responsible for warming the incoming air to assist with engine starting and cylinder combustion.
When the engine coolant temperature is below 40°C (104°F), the Glow Plug Control Module (GPCM) activates the IAH. The IAH is connected to the GPCM through various circuits, including the temperature signal circuit, command 1 circuit, command 2 circuit, voltage signal circuit, current signal circuit, and feedback signal circuit. If there is a fault detected in any of these circuits, the P154A fault code will be triggered. This fault code indicates that there is an issue with the feedback signal circuit of the IAH.
It is important to address this problem as it can affect the proper functioning of the IAH and impact engine performance. A diagnostic scan tool can be used to identify the specific cause of the fault and determine the necessary repairs or replacements needed to resolve the issue.
