What Does P1295 Mean?
The PCM has detected multiple low-side short circuits in the Bank 1 fuel injector control circuits. This means one or more injector ground circuits are shorted to ground or to each other, causing improper injector operation.
Safety Warning
Engine will run poorly or not at all, potentially stalling without warning. Vehicle should not be driven until repaired.
Common Causes
40%
Chafed wiring causing short to ground
25%
Failed fuel injector with internal short to ground
20%
Damaged injector connector with crossed pins
10%
Water intrusion causing short in connector
5%
Failed PCM low-side driver circuit
Diagnostic Steps
1
Step 1: Disconnect all Bank 1 injectors and inspect connectors for damage, corrosion, or oil contamination
2
Step 2: Measure resistance from each injector low-side control wire to ground with injectors disconnected (should be open circuit/infinite resistance)
3
Step 3: Inspect wiring harness routing for chafing against engine components or heat shields
4
Step 4: Test each Bank 1 injector coil resistance and check for shorts to ground
5
Step 5: If wiring and injectors test good, suspect PCM internal driver short
Estimated Repair Cost
$150 - $1,500
Parts + labor, varies by vehicle and location
