113 is a fault in the injectors if you have a Regina fuel system. You have a Bosch 2.4 FI since it is a turbo. The table says it is a fault in the O2 sensor or wiring, maybe, and that is a big maybe. Did you clear the code and it came up again?

Has basic tune up stuff been done? Plugs, cap rotor, air cleaner, vac hoses, clean T body, check the intake hoses for holes, tighten the clamps as required. Actually that is the first thing to look at before replacing parts.

Again, the fault may be true or just a hint. How is the gas mileage? After catching up on normal maintenance items, I’d look at the O2 sensor, the fuel pump relay, fuel injector relay, and the power stage in that order. You can test the O2 sensor at not cost and resolder the FI relay and fuel pump relay but I’d be prepared to replace them if you have to go that far. There have been several recent posts on just bad contacts in the fuel injector relay. Cleaning the contacts may be a temporary fix though.

Other possibilities, fuel pumps and fuel pressure regulator among others.

Good luck, Tom
