Question about 2007 Toyota Corolla CE

1 Answer

How do I reset the ECU on my 2007 Corolla CE?

I had to disconnect the battery in order to remove the fuel pump and replace the sending unit. The car idled just fine before I did that. Now, the engine idles (roughly) at around 500rpm. I took the car out on the road and did some starts, stops, and slow downs of varying intensity. But, the problem still persists. Will this go away on its own, or is there a procedure for resetting the ECU that I'm not aware of. Thank you. Mark B Handler

How to install fuel filter&pump


  • De-pressurize the Camry's fuel system. With the gas cap open (to release pressure in that location), open the fuse/relay panel under the hood and remove the relay labeled "C/OPN." Start the engine and let it run until it stops. Disconnect the battery's negative cable.

  • Detach the rear seat from the car. Lift up the front edge of the seat bottom cushion, disconnect the mounting bolt underneath and remove the cushion. Pull up the seat back locks, flip the seat backs down and remove the mounting bolts.

  • Remove the service hole cover from the floor under the seat concealing the fuel pump/sending unit.

  • Disconnect the fuel line and electrical connectors from the fuel pump unit. Remove the retaining bolts and withdraw the unit carefully out of the fuel tank.

  • Release the clips on the fuel pump assembly's plastic support with a screwdriver to remove the support. Then pull off the rubber isolator, remove the fuel sock filter and disconnect the electrical connector from the top of the assembly. You can now withdraw the fuel pump from the housing.

  • Connect the new fuel pump into place on the assembly housing. Reassemble the fuel pump/sending unit in order, from the electrical connector to the fuel sock filter, rubber isolator and bottom plastic support.

  • Place the pump unit back within the fuel tank and reattach the bolts. Reconnect the electrical connectors and the fuel line. Reattach the rear seats.

  • Replace the "C/OPN" relay, reconnect the negative battery cable and fill the fuel tank if it is empty.

  • Pressurize the Camry's fuel system by turning the ignition on for a couple of seconds. Then turn it off for ten and repeat this five to ten times.
