What would cause an 02 t&c speedometer to stop working & not shift into overdrive? Codes p1193 & p1684 came up on dash. Van was shifting fine before that


My first guess would be a defective speed sensor in the transmission.
Neither of the codes you mentioned involve the speedo problem. Code 1193 is for a problem with the intake air temp sensor, and code 1684 means the engine computer has lost battery power at some point in time.

Speed sensor issues error code P0500


sounds like a transmission issue could need a transmission fluid flush then you should be fine the first indicator that your transmission is going bad is the first gear and reverse but since its overdrive probably just a tranny fluid issue hope that helps

Trubleshooting p0502 honda element


P0502 is a Vehicle speed sensor issue:
P0502 Description The vehicle speed sensor outputs a 4 pulse signal for every revolution of the rotor shaft, which is rotated by the transmission output shaft via the driven gear. After this signal is converted into a more precise rectangular waveform by the waveform shaping circuit inside the combination meter, it is then transmitted to the ECM. The ECM determines the vehicle speed based on the frequency of these pulse signals.

- Speedometer may not work properly
- Transmission shifting problem Possible Causes - Vehicle speed sensor harness or connectors is open or shorted
- Vehicle speed sensor
- Combination meter
- Faulty ECM.
