Question about 1989 Jeep Wrangler
I have one grand cherokee 1998 4.0L, I have problems with the throttle position sensor (code=P0122), the motor to be working correctly, some time , accelerates stop and later the motor is only standardized, already changes the throttle position sensor, map sensor and the CPU, but it follows the fault intermittent help me.
The throttle position sensor on my 98 Grand Cherokee was intermittent. When the cruise control was on, the transmission would sometimes downshift as if a sudden acceleration was needed, even though it was not.
The TPS is hermetically sealed, so I cut it open with a Dermal tool. The wiper inside was bent. After restoring the shape of the wiper and re-assembling the sensor with RTV sealant, it has worked perfectly since.
