P2154: Affordable Fix For Your Car’s Fault Code
The automobile fault code P2154 indicates a problem with the vehicle’s speed sensor circuit.
The estimated repair time for this issue is 1.0 hour. The cost of fixing this problem can vary depending on the auto repair shop, but it is common for them to charge between $75 and $150 per hour. Other factors that may influence the cost include the severity of the issue, the type of vehicle, and the location of the repair shop.
P2154: Your Car’s Throttle Position Sensor Needs Attention
The P2154 code is related to the high control circuit of the fuel injector in cylinder 3. The Engine Control Module (ECM) supplies voltage to each fuel injector on the high control circuits. The ECM energizes each fuel injector by grounding the low control circuit of the fuel injector.
When the ECM detects that the fuel injector high voltage supply circuit is shorted to voltage for more than 2 seconds, it disables the affected fuel injector(s).
This results in the P2154 code being set and the fuel injector in cylinder 3 being disabled.
FAQ
If you’re experiencing the P2154 fault code, your engine light may be on. This could be due to a faulty fuel injector 3, an open or shorted fuel injector 3 harness, a poor electrical connection in the fuel injector 3 circuit, or a faulty engine control module (ECM). To fix the issue, check the possible causes listed above and visually inspect the related wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to a P2154 fault code, there are a few possible causes to consider. One of them is a faulty Fuel Injector 3, which can be fixed by visually inspecting the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. Make sure to also check for an open or shorted Fuel Injector 3 harness and a poor electrical connection in the Fuel Injector 3 circuit. Lastly, consider the possibility of a faulty Engine Control Module (ECM).
While a faulty Engine Control Module (ECM) is listed as a possible cause of the P2154 fault code, it is not a common cause. The most common cause of this code is a faulty Fuel Injector 3, followed by issues with the injector’s harness or circuit connection. To fix the issue, it is recommended to visually inspect the wiring harness and connectors for any damage or corrosion, and check for broken or bent pins.
Wrap Up
If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to a faulty Fuel Injector 3, Fuel Injector 3 harness, poor electrical connection, or a faulty Engine Control Module (ECM).
Check the possible causes, inspect the wiring harness and connectors, and look for damaged components or corroded pins.
