Check Engine Light After Tune-Up 1993 240sx coupe

One of my injectors quit on me so I replace it. At the same time I replace the spark plug wires and the spark plugs. Now ater I turn it on I get a CEL so I pulled m ECU and it gives me codes 13,14, and 34 which are 13 E Engine temperature sensor circuit14 E Vehicle speed sensor circuit34 Detonation sensor circuit

Any clue why it would do this and/or what do these mean? What would need replaced/fixed to solve this problem? I searched and couldn't get any solid answers

*UPDATE* Turns out that when I removed the fuel rail I unplugged a sensor unknowingly and that is what caused the CEL. Its all good now and running like a top.

The one that trips 13 E Engine temperature sensor circuit14 E Vehicle speed sensor circuit34 Detonation sensor circuitat the same time. I don't know which one it was. Was at the front of the engine by the near the front header.

The temperature sensor is at the front. Im guessing that the other codes were stored in memory from the past.

Cool, thanks for the info. I cleared the ECU when I figured out the problem.
