Either you must relearn the computer or there is something wrong with the wiring or ground(behind the left cylinder head). I am just guessing it's a 3.3L but either way you must use a scan tool to reprogramm the PCM. It must be done when replacing parts. I know it's a pain but it will give you a chance to check if there are other codes also.
