2010年9月17日 · Hello everybody! I'd like to see if anyone else has any ideas. My 2000 fwd RX300 (145K) has a P1730 code. It drives and shifts fine and I've tested both speed sensors and they are within normal limits and so is the wiring to the ECM. I know the next logical step is to replace the ECM to see if th...

Now Advance Auto parts read the check engine light and code p1730 comes up as rev sensor. ??? What is that? Does it also inhibit shifting into fourth? Or does it actually mean Knock sensor?
