What Does P2293 Mean?
The secondary fuel pressure regulator (Regulator 2) is not performing within expected parameters. This indicates the regulator cannot properly maintain or control fuel pressure in systems with multiple regulators or staged pressure control.
Common Causes
35%
Failed fuel pressure regulator 2 valve mechanism
25%
Vacuum line leak or restriction affecting regulator control
20%
Electrical control circuit fault to regulator solenoid
15%
Contaminated fuel affecting regulator operation
5%
Fuel return line restriction for regulator 2 circuit
Diagnostic Steps
1
Step 1: Monitor fuel pressure regulator 2 command and actual pressure feedback using scan tool
2
Step 2: Test electrical control circuit for proper voltage and ground to regulator 2
3
Step 3: Inspect vacuum lines (if applicable) for leaks, cracks, or restrictions
4
Step 4: Measure fuel pressure at regulator 2 location and compare to specifications
5
Step 5: Check for fuel contamination and inspect regulator filter screen if accessible
Estimated Repair Cost
$200 - $650
Parts + labor, varies by vehicle and location
The secondary fuel pressure regulator (Regulator 2) is not performing within expected parameters. This indicates the regulator cannot properly maintain or control fuel pressure in systems with multiple regulators or staged pressure control.
The most common cause of P2293 (Fuel Pressure Regulator 2 Performance) is: Failed fuel pressure regulator 2 valve mechanism
Typical repair costs for P2293 range from $200 to $650, depending on the vehicle, location, and whether you do it yourself or go to a shop.
May cause poor engine performance, reduced power, and fuel economy issues. Generally does not create immediate safety concerns but should be repaired promptly.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2293 to identify the root cause.
