Hello wonderful people. I have a 2005 Toyota corrolla with engine code P0606 ecm/pcm processor.
The car formally had code p0500 vehicle speed sensor, and speed sensor wiring was reconnected as lose wire was seen, brakes and wheel was also worked on
Check engine light is currently on, ABS, brake and tire pressure too, speedometer does not work.
Car also stalls occassionally when coming to a halt

Please help

PCM/brain box is likely the issue

Have your ABS wheel speed sensor checked and possibly replaced the faulty ones. Speedometer failure most of the time is as a result of bad front wheel ABS speed sensor on the driver side.
If you want to know which sensor is faulty, use digital multimeter to check for resistance at the contact point (harness) of the sensor. A good working sensor should read 500-800+ Ohms, while a bad one read less than 300. Do this on the 4sensors.

NB:1) A regular OBDII scanner may not be able to tell the exact wheel with a bad sensor, except a little rugged scanner. Hence the use of Ohms meter.
2) Faulty speedometer is as a result of bad front speed sensor.
3) All the above are simple DIY.

Thanks will get a good technician to do this, changed the plugs and stalling stopped. Pcm code also gone but the P0500 came right back up so know the culprit
