What Does U1130 Mean?
This code specifically indicates the receiving module cannot obtain valid fuel system data over the network, likely from the PCM. This affects fuel delivery monitoring, gauge display, or fuel system control coordination.
Common Causes
40%
Failed powertrain control module or PCM communication circuit
30%
Network bus wiring issue between PCM and receiving module
15%
Failed instrument cluster unable to receive fuel data
10%
PCM power or ground circuit failure preventing communication
5%
Corrupted PCM software or calibration affecting data broadcast
Diagnostic Steps
1
Step 1: Verify PCM is communicating on network by checking for other PCM-related DTCs or monitoring scan tool PIDs
2
Step 2: Check PCM power and ground circuits - verify battery voltage at power pins and less than 0.1V at grounds
3
Step 3: Inspect engine harness connectors and firewall pass-through for corrosion or damage
4
Step 4: Monitor fuel system PIDs on scan tool to verify PCM is calculating fuel data internally
5
Step 5: Check for PCM software updates or recalibration requirements from manufacturer service information
Estimated Repair Cost
$150 - $1,500
Parts + labor, varies by vehicle and location
This code specifically indicates the receiving module cannot obtain valid fuel system data over the network, likely from the PCM. This affects fuel delivery monitoring, gauge display, or fuel system control coordination.
The most common cause of U1130 (SCP (J1850) Invalid or Missing Data for Fuel System) is: Failed powertrain control module or PCM communication circuit
Typical repair costs for U1130 range from $150 to $1,500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
May result in inaccurate fuel gauge readings and potential fuel starvation without warning. Monitor fuel level manually and refuel conservatively until repaired.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U1130 to identify the root cause.
