Welcome to the forum. Always diagnose first. Fault codes don't necessarily mean that the part is 'bad'. The parts that you replaced are likely OK. The wiring to or from, or the PCM (rarely) can fail.
Multiple parts usually don't fail all at the same time together, it sounds like a wiring problem? You need to find out what all the fault codes have in common or what circuits/grounds they may share together.
The fault code 'P' number is helpful to know what you are looking for. i.e. - did it fail high or low?
Do you have the actual fault codes?
Wiring problems (shorts or opens) can be intermittent, which would explain why it might have been OK at first.
4-cylinder? Has it had any recalls done? What are the fault codes that we are dealing with?
