value.
TP sensor circuit shorted to VCC or ground circuit open, L Sensor voltage is lower than specified value, TP sensor circuit open or shorted to ground or VCC circuit open
do you know how to test circuits and so forth? service manual helps some but they expect you know what you are testing for and only give the values required soa youtube video is helpful in this situation, you could check and clean the connectors so forth and eliminate that..
