The P0122 is a throttle sensor code.
yes when i reset the dct i will be able to clear it but when i try to run diagnostics readings the code and PO452 ,and PO452 p/d as well as the PO122
OK, if the P0122 resets then you have a bad sensor, bad wiring or the the PCM. I suggest to check the wiring and the terminals in the connector. IF they are good then try a sensor.
As for the P0452, same thing, but the sensor is not the issue if you tried it. The wiring and terminals are common for failing.
do you think that any of these codes have anything to do with the transmission not shifting in passing gear?
Yes the P0122 will. The computer needs to know the throttle position to know what gear to put it in.
I have been leaning toward the ecm its self
I would not just yet. Far too many are replaced and not the cause.
ok i will check my connections once again and run my scans,The voltage is about 5 volts at the connectors right?
Yes they use a 5v reference.
i will contact you as soon as i check this out ok? thank you
You can reply at any time for follow up information regarding this issue, even after you accept my answer and I will reply.
No bulletins on this issue.
Did you do a pin drag test? We do something called a pin drag test. This is done one the female terminal with a new male terminal from the GM kit. We insert it and then see how it feels to pull it out. If there is no resistance and the terminal is loose in there, then we know the female terminal is stretched.
What further info do you need?
This sensor will not cause the low fuel message, that is a separate sensor, but is read through the PCM. It may be, but often it is wiring.
YOu did check under the fuse block? Mice love that area.
Check that first and see. LEt me know
