Need help ASAP (high/low pressure sensor)

[WP1]

Hi All,

So driving the car yesterday on my way to work, the car started shaking and lost power. Then got the message of Engine Malfunction, operating at reduce power output.

So I panic and had it towed to the dealer.

1. Dealer it saying High Pressure rail sensor needs to be replace $400

1. Also recommends changing the Low sensor at the same time $800

Why this cost double?

So, I changing the High Rail Sensor.

What is the like-hood of the Low sensor to go bad?

Also the fuel injectors were replaced under warranty back in April this year. So, do the injectors have to do with the sensor going bad?

Thanks,

Over the pass year I have spend closed to $4K
