Getting a P1768 code… Stuck in Limp mode, and reader says we are going 88 when we are actually going 55… Thoughts? ---

what reader? do you mean the speedometer? from the internet: (search for p1768 code chrysler) this code is for the transmission control relay and below is a list of possible causes LOW BATTERY VOLTAGE CAUSING SYMPTOM FUSED B(+) CIRCUIT TO TRANS CTRL RELAY OPEN TCR GROUND CIRCUIT OPEN TRANSMISSION CONTROL RELAY CIRCUIT OPEN TCM PIN 16 TO TCR OPEN OR BAD CONNECTION TCM PIN 17 TO TCR OPEN OR BAD CONNECTION TRANSMISSION CONTROL RELAY DEFECTIVE NO OUTPUT FROM TRANSMISSION CONTROL RELAY TCM TRANS RELAY CONTROL CIRCUIT SHORT TO VOLTAGE INTERMITTENT CODE P1768 ---

Don’t know why you are in limp home mode but it sounds like you speedometer display has switched to kilometers per hour. ---

If your battery is over 3 years old, try a new one. ---

It’s the code reader. ---

The code reader showed 88… Not the actual speedometer. ---

The code reader shows you your speed??? ---

The more sophisticated code readers can read the car’s sensors individually, so are able to read the vehicle speed sensor. That’s why the insurance companies want to plug electronic monitor boxes onto the obd II connector full time, so they know how fast the owner drives the car. Drive too fast, your rates go up, or you get dropped… Th OP’s code reader must display the output of the vehicle speed sensor in km/hr units rather than miles/hr. ---

> [@oldtimer-11](#): > > The code reader shows you your speed??? When my brother got a Harbor Freight code reader for about $90, he plugged it in to my Insight, and as I drove, he told me real-time coolant temp, spark advance, and other stuff. ---

Exactly so. My scanner also gives all that internal data. And, when I hooked up to the government pickup they were using to pickup garbage on streets where the big garbage truck can’t go, it showed coolant temp at -40, also a synch problem in the motor. And, yes, if driving (careful of distractions) it tells you road speed.
