P2155: Your Car’s Throttle Position Sensor Needs Attention
The P2155 code is related to the fuel injector circuit in cylinder 4 of the engine. 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 not to factory specifications, it disables the affected fuel injector(s). This results in the P2155 code being set, indicating a problem with the high control circuit of the fuel injector in cylinder 4.
FAQ
If you’re experiencing the P2155 fault code, your engine light may be on. This could be due to a faulty fuel injector 4, an open or shorted fuel injector 4 harness, a poor electrical connection in the fuel injector 4 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 the P2155 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, you may have a faulty Fuel Injector 4, an open or shorted Fuel Injector 4 harness, a poor electrical connection in the Fuel Injector 4 circuit, or a faulty Engine Control Module (ECM). To fix this issue, you should 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.
While a faulty Engine Control Module (ECM) is listed as a possible cause of the P2155 fault code, it is not a common one. The most common cause is a faulty Fuel Injector 4, followed by issues with the fuel injector harness or poor electrical connections. 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
