DTC P1642 is for a loss in CAN communication. You will need to read the codes from the other modules to see which one is the culprit. From your description is does sound like the CAN network went down. It may be a problem with the inertia switch. It may have partially tripped causing this problem.

See your owner manual for the location of your inertia fuel cutoff switch. It cuts off power to the fuel pump in an accident.

CAN is the communication network where all teh computers in your car talk to one another. There appears to be a problem intermittently here.

I had that same problem on a trans years ago, had to go to neutral and back to drive to get drive. I just delt with it in that manner. It doesn't do any harm to the trans at all doing that. Your best getting a specialist do a diagnostic on your trans eventually.

Are you sure the trans is in 3rd. Pull the stick into low gear accelerate shift to 2nd about 20 mph shift to 3rd about 35 mph then 4th about 50 mph. This will let me know how to go further with your problem. If you do this proceedure write the results on this Great FixYa Page!

Check engine light with following codes p 1529 p0720 p0715


P1529 indicates that your TCM asked the ECM to turn on the check engine lamp.

The range switch and the output speed sensors are the items that are abnormally affecting the operation of the transmission. The diagnostic logic in your computer can distinguish these issues from one another, so you'll definitely want to do both. You have no diagnostic code for the input speed sensor (P0715) listed, so I have made no recommendation to replace it. In my opinion, it's not a labor-intensive repair, so I wouldn't recommend replacing it unless you have reason to believe it's bad.

DTC - P0720 (OUTPUT SHAFT SPEED SENSOR SYSTEM)
Code No. P0720 Output shaft speed sensor system
If the output from the output shaft speed sensor is continuously 50% lower than the vehicle speed for 1 second or more while driving in 3rd or 4th gear at a speed of 30 km/h or more, it is judged to be an open circuit or short-circuit in the output shaft speed sensor and diagnostic trouble code No. P0720 is output. If diagnostic trouble code No. P0720 is output four times, the transmission is locked into 3rd gear or 2rid gear as a fail-safe measure.
Probable cause
Malfunction of the output shaft speed sensor
Malfunction of the transfer drive gear or driven gear
Malfunction of connector
Malfunction of the TCM

DTC - P0715 (INPUT SHAFT SPEED SENSOR SYSTEM)
Code No. P0715 input shaft speed sensor system
If no output pulse is detected from the input shaft speed sensor for 1 second or more while driving in 3rd or 4th gear at a speed of 30 km/h (19 mph) or more, it is judged to be an open circuit or short-circuit in the input shaft speed sensor and diagnostic trouble code No. P0715 is output. If diagnostic trouble code P0715 is output four times, the transaxle is locked into 3rd gear or 2nd gear as a fail-safe measure.
Probable cause
Malfunction of the input shaft speed sensor
Malfunction of the underdrive clutch retainer
Malfunction of connector
Malfunction of the TCM

Is needed replace.
