What Does P2283 Mean?
The PCM has detected an electrical fault in the injector control pressure (ICP) sensor circuit on diesel engines or high-pressure fuel systems. This sensor monitors the hydraulic pressure used to actuate fuel injectors.
Safety Warning
May cause no-start condition, severe performance loss, or engine stalling. Do not drive if engine is running poorly or stalling occurs.
Common Causes
35%
Damaged wiring or connectors in ICP sensor circuit
30%
Faulty injector control pressure sensor
20%
Corroded or loose electrical connections at sensor
10%
PCM internal fault or software issue
5%
Damaged sensor mounting causing intermittent connection
Diagnostic Steps
1
Step 1: Inspect ICP sensor connector for corrosion, damage, or loose pins
2
Step 2: Check wiring harness from sensor to PCM for chafing, cuts, or damage
3
Step 3: Measure voltage and ground at ICP sensor connector with key on, engine off
4
Step 4: Test ICP sensor resistance and compare to specifications
5
Step 5: Monitor ICP sensor signal with scan tool during engine operation
Estimated Repair Cost
$150 - $600
Parts + labor, varies by vehicle and location
The PCM has detected an electrical fault in the injector control pressure (ICP) sensor circuit on diesel engines or high-pressure fuel systems. This sensor monitors the hydraulic pressure used to actuate fuel injectors.
The most common cause of P2283 (Injector Control Pressure Sensor Circuit) is: Damaged wiring or connectors in ICP sensor circuit
Typical repair costs for P2283 range from $150 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
May cause no-start condition, severe performance loss, or engine stalling. Do not drive if engine is running poorly or stalling occurs.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2283 to identify the root cause.
