P0193 on Nissan
Fuel Rail Pressure Sensor "A" Circuit High
P0193 on Nissan vehicles indicates fuel rail pressure sensor "a" circuit high. Au7o has documented this code across 1 Nissan model — most commonly on Juke. The PCM detects a fuel rail pressure sensor 'A' circuit signal above the normal range (too high), typically caused by a short to voltage, open ground, or failed sensor.
Common Causes of P0193
- •Short to voltage in signal wire
- •Open ground circuit
- •Faulty fuel rail pressure sensor
- •Corroded connector terminals
- •Wiring damage
P0193 on Nissan by Model
Nissan Juke(1 issue)
- Fuel Pressure Sensor Loosens and Leaks Fuel (Recall 14V683 / PC618)2011-2014
The fuel pressure sensor threaded into the high-pressure fuel line on the MR16DDT engine was not sufficiently torqued at the factory, so it can loosen with vehicle usage and cause a fuel leak. A fuel leak in the presence of an ignition source could cause an under-hood fire. Nissan issued multiple related campaigns (early 12V069, PC618, and expanded recall 14V683) covering 2011-2014 Jukes.
