How serious is P0193?

mark2410 · Oct 25th, 2021, 20:34

so as my cars prefer being at the garage than at home today the C70 spat out P0193 which is apparently a fuel pressure problem. The car ran fine, i didnt really notice anything but clearly something happened.

So, how big a deal is it? should i be worried

It'll be the Bosch Fuel Pressure Sensor on the left hand side of the fuel rail.
They deteriorate over time on these turbo 5 cylinder volvos.

Volvo Part no: 31272732
Bosch Part no: 0261230239

Plenty on Ebay for under £40.00

DIY job really... It's held on by 1 Torx screw but not much room so you need slim tools, something like this:

find the Fuse for the fuel pump ,in the fuse board passenger footwell
remove it
start the engine, let it run till it cuts
keep attempting to start till it wont

Disconnect the battery
Fuel rail, the Other end to the sensor there is a schrader valve,remove the valve cover (if fitted) Lots of rags under, press the center to release any remaining pressure replace cover (if fitted)

loads of rags under the sensor itself
unplug the elec connection , take the screw out
Dont drop the screw
no really Dont drop the screw !

new oring, new sensor, refit the screw (Dont drop it) refit the connector
battery back on
*take care NOT to put arm Through the steering wheel to spin the car over as airbag "oh bugger" would result in broken arm

done

I changed a pressure sensor on my D5, no improvement, also change the fuel filter!
Cured it!
I am not saying that is your problem but it won't hurt to do it!🙂
