Well I think I found the answer
Jeep Grand Cherokee (WJ) with 4.7L engine. Dodge products with 4.7L engine.
The check engine light is on. Has any or all of the following DTCs: P0201 injector#1 control circuit, P0202 injector #2 control circuit, P0203, P0204, P0205, P0206, P0207, P0208. Fault is probably intermittent, and there is possibly no driveability problem associated with it.
A fault in the TPS (throttle position sensor) causes signal noise, which the PCM interprets as an injector circuit fault. This condition is very rare.
Replace the TPS to correct the condition.
