Trouble code P0202 means: Injector circuit malfunction - cylinder #2
Fault code P0202 indicates a malfunction in the fuel injector circuit for cylinder 2. This can be caused by wiring issues, a faulty fuel injector, or a problem with the Engine Control Module (ECM). It is important to diagnose and address the root cause of the issue to prevent potential engine misfires or poor performance.

Trouble code P0202 means: Fuel Injector 2 Control Circuit Malfunction Trouble code P1684 means: The battery has been disconnected within the last 50 starts
The P0202 code indicates a problem with the fuel injector circuit for cylinder 2 on a Jeep 4.0. To fix this issue, start by checking the wiring and connectors leading to the injector for damage or corrosion. If the wiring is intact, test the injector itself for proper operation using a multimeter or by swapping it with another cylinder's injector to see if the code follows. If the injector and wiring are both functional, the issue may lie in the Engine Control Module (ECM) and may require further diagnosis or replacement.
#2 fuel injector control circuit malfunction.
P0202 is injector number 2 circuit open. P2074 is map sensor TPS correlation. P0108 is map sensor circuit high. With all three codes I would think the wiring harness has been pinched or damaged near the rear valve cover, driver side.

P0202 relates to the fuel injector on cylinder No2. The code SUGGESTS that the injector has no electrical power to it. These work on a constant 12V feed and the ground is supplied by the ECU by a predetermined map. i.e. open circuit = no complete electrical circuit. The most effective way of checking this is with an oscilloscope. A multi meter may not capture the power at the correct time due to the slow refresh rate.
