The input clutch solenoid valve is operated by the TCM in relation to the data received from the park neutral position switch, throttle position sensor and vehicle speed sensor. With this data, the shift program is decided upon. Without it, shifting performance will be affected, and a P1752 OBDII code will be set.
How Serious is the Code?
A P1752 Nissan diagnostic trouble code is moderately serious, and can impact transmission performance.
Symptoms of a P1752 include:
- Unusually hard shifts
- Erratic transmission behavior
- Wiring and/or connector damage
- Failed input clutch solenoid valve
How to Diagnose the Code?
The first step to diagnosing a P1752 OBD2 code is to inspect the wiring and connectors scratch along the transmission wiring harness for signs of damage. If no shorted wires, loose ground connections, or corroded/broken connectors are found, then the input shaft clutch solenoid valve should be tested.
What Repairs Will Fix P1752?
- Repair or replace damaged wiring or connectors
- Replace input clutch solenoid valve
