What Does P2286 Mean?
The ICP sensor signal voltage is above the maximum threshold expected by the PCM. This indicates a short to voltage in the circuit, an open circuit condition, or a failed sensor providing abnormally high readings.
Safety Warning
May cause no-start, hard starting, severe performance loss, or stalling. Vehicle should not be driven until repaired.
Common Causes
40%
ICP sensor internal failure or open circuit
25%
Open circuit in sensor signal wire or poor connection
20%
Sensor signal wire shorted to voltage source
10%
Corroded or backed-out pins in sensor connector
5%
PCM internal fault on sensor input circuit
Diagnostic Steps
1
Step 1: Disconnect ICP sensor and measure voltage at sensor connector (signal wire should drop to ~0V)
2
Step 2: Check for proper 5V reference and ground at sensor connector
3
Step 3: Test sensor signal wire for short to voltage or open circuit
4
Step 4: Inspect sensor connector for spread terminals, corrosion, or backed-out pins
5
Step 5: Test ICP sensor by measuring output voltage at various pressures if possible
Estimated Repair Cost
$150 - $800
Parts + labor, varies by vehicle and location
The ICP sensor signal voltage is above the maximum threshold expected by the PCM. This indicates a short to voltage in the circuit, an open circuit condition, or a failed sensor providing abnormally high readings.
The most common cause of P2286 (Injector Control Pressure Sensor Circuit High) is: ICP sensor internal failure or open circuit
Typical repair costs for P2286 range from $150 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
May cause no-start, hard starting, severe performance loss, or stalling. Vehicle should not be driven until repaired.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2286 to identify the root cause.
