I have a 2009 Dodge Journey, and it recently started displaying the P0201 code, so I changed the spark plugs. Cleared the code and drove it for about 15 minutes and it was like new. The next day I drove it until the engine temps came up to normal and the code came back. Parked it until the morning and it got really cold last night, and this morning it drove like new again. Drove it a little later, temps came up to normal, gat the code again. Anyone got any ideas?

The P0201 code indicates an issue with the injector circuit on cylinder 1. Since the code returns when the engine warms up, it’s likely related to thermal expansion affecting an electrical component or connection. Here are some steps to consider:
-
Check Injector and Wiring: Inspect the injector itself and its wiring harness for signs of wear, especially near connectors or wires that might expand when heated. You may have a loose or damaged connection that fails when warm.
-
Test the Injector: You can use a multimeter to test the resistance of the injector. Compare it with the specs; if the reading is off, the injector may need replacement.
-
Inspect the PCM: Sometimes, the Powertrain Control Module (PCM) can fail intermittently. While less common, it can cause injector circuit codes to appear when the module or connections heat up.
-
Inspect Grounds: Ensure all engine grounds are solid and corrosion-free. Ground issues can sometimes lead to intermittent injector codes.
Thermal expansion issues can be tricky, but a systematic approach should help in pinpointing the exact cause.
