Did anyone’s Infiniti receive the code P1757? If so how did you fix it, where did you go and what did you do? Please help! My G35 lags on me every now And then. I’ll press the gas peddle and it will struggle to accelerate. It doesn’t happen always but when it does it’s a struggle to get it to walk. Honestly any info will help

 

Remove the TCM/Valve body, inspect the wiring from the front brake solenoid to see if it's damaged. The earlier ones like yours don't have the flat pin assembly which is notorious for breaking at the harness so I'm guessing you will end up replacing the front brake solenoid itself.

thank you so much! I’ll definitely try this (:

 

Just a heads up, once you identify exactly which of the 5 different valve bodies you have in your car you can get a remanufactured Sonnax from rockauto.com for $300+core. Depending on mileage (guessing it's high if you're having solenoid issues) you should probably just replace the entire VB with a rebuilt unit just so you don't have to keep tearing it apart every year to replace another failed solenoid.

EDIT: Or get a solenoid kit and replace them all at once, personally I'd go with the Sonnax rebuilt unit over a cheap set of chinese solenoids and good solenoids are expensive enough that you might as well just get an entirely rebuilt VB.

 

thanks so much! This is soooo helpful
