SOURCE: fault codes P0722 and P0717
You just need to replace the sensors. If you are mechanically inclined, you can do it yourself. If you don't feel comfortable working on an expensive transmission, take it to the dealer.
SOURCE: need to know what these codes mean for hyundai
P1529- TCM MIL request signal failure
P1404- DTML Heater circuit failure
P0722- ATM Output speed sensor no signal
All these together indicate a possibly cut wiring harness failure, or other major circuit issue.
SOURCE: I Have A 2000 Hyundai
P1529 - MIL light request
P0722 - Transmission Pulse Generator B. The Pulse Generator detects the revolution of the idler gear parking
pawl lock gear and emits a pulse signal. The pulse signal is sent to the
Transmission Control Module (TCM) which converts it into vehicle speed. The code is detected when the Pulse Generator B failed to provide a signal to the TCM upon initial movement of vehicle.
Symptoms:
- Engine Light On (or Service Engine Soon Warning Light)
- Speedometer improper reading
- Possible shifting problems
Possible Causes:
- Pulse Generator B harness or connectors
- Pulse Generator B circuit is open or shorted
- Pulse Generator B
SOURCE: have 2 codes (P1529) and (P0722) what sensors are
P1529 means nothing more than the TCM (transmission control module) has
requested that the ECM (engine control module) turn on the check engine
lamp.
On top of
the ******, by the selector lever, there is the range switch. Disconnect, clean
therminals, add some dielectric gears to the terminals, and reconnect.
Disconnect negative battery terminal for 30+ sec., reconnect terminal, drive car
and see if MIL come on again.
P0722 indicates a problem with the pulse generator B (output speed sensor) signal. Hyundai has identified an issue where the transmission control module (TCM) improperly interprets induced signals in the vehicle speed sensor signal wire as signals from the speed sensor itself, making the TCM think there is a problem with the pulse generator signal. Information on the problem is in TSB 03-40-016. In most cases, reprogramming the TCM solves the issue, but this work must be done by the dealer. I'd expect you'd pay one to two hours of labor for the diagnosis and reprogramming.
Trouble Code: P0722
A/T Pulse Generator 'B' Sensor Circuit Malfunction
Possible Causes:
Pulse generator 'B' (+) or (-) circuit is open or shorted to ground .
Pulse generator 'B' is damaged or has failed.
TCM has failed .
TSB 01-40-006-1 (12/01) contains information about this code.
Trouble Code: P01529
Customer Snapshot Request Error
Possible Causes:
Transmission control module error.
Check for trouble codes in the transmission control module.
TSB 1-40-005 (3/01) contains information about this code. I have info. on these 2 codes,will search more for the others.
