So my TCS light and CEL came on I scanned it with a generic OBD and got P0122 Throttle position sensor circuit low input. Is this sensor replaceable without replacing the throttle body. Also shifts harshly into gear R,D etc. is this just the sensor or could something wlse be wrong with it. This issue is also intermittent These lights come on every so often. Any ideas........or anyone else have this problem with their 03 TL
