SOURCE: Check Engine Light with Code P0072 on 2004 Volvo XC90

Grounding issue "Circuit low" = ground wire problem or another system on the same circuit using too much current.

Check all wiring issues and then correct the issue to have the code go away :)

SOURCE: Check engine light is on. OBD reads p0191 &

Replacement of the fuel pump would be the case here,unless the fuel filter needs to be changed.To find out,remove the fuel filter,and blow threw it with your mouth,kinda tast bad but it will tell you if the fuel filter is restricted.You should be able to blow threw it easy.

Possible problem with the alternator not putting out enough voltage. I had the same problem with my 2002 XC70, putting in a new alternator fixed it. I used a local mechanic who I found on the car talk web-site. Low Cost Volvo parts can be purchased at FCP Groton.

P0191 is injector pressure sensor system performance. Nothing on the other code with the letter mixed in. I would erase it and see if it comes back.

P0191


You need to have the fuel pressure checked, to see if the fuel pump or fuel filter may have a problem. The code is for the Fuel Rail Pressure sensor, and the reading from it is out of range.

Hi. I have a 2003 Ford Focus LX. A few weeks ago, I was driving back to Florida from South Carolina. About six hours into the drive, my car stopped accelerating. I would push down on the gas pedal and...


Diagnostic Test code (DTC) P0191 has a generic description which reads "Fuel Rail Pressure (FRP)Sensor Circuit Performance"

This code sets when the Powertrain Control Module (PCM) is monitoring the fuel rail pressure sensor signal under certain driving conditions. The FRP sensor varies return voltage to the PCM to indicate the fuel pressure at the fuel rail on the engine. DTC P0191 sets when the voltage received from the FRP is above or below the expected "range" or "threshold".

The possible causes of this code are:

> High fuel pressure
> Low fuel pressure
> Damaged Fuel Rail Pressure Sensor (FRP)
> Excessive resistance in FRP circuits.
> Low or no fuel

With all of that said, I would recommend that if you have more than 30,000 miles on your current fuel filter, I would try that FIRST. Replace the filter and clear the code. If the code returns, then diagnostics will need to be performed to find the actual cause.

Unless is was the one doing the testing I can not say that it will fix the problem. I would check the fuel pressure, the fact you have a rich code (P0172) means you may have excessive fuel pressure and the sensor is reading that.I assume this is a four or six cylinder and you have only one bank of cylinders. Check the fuel pressure before you do any parts replacing.
