Injector Control Pressure Sensor Circuit Malfunction
The P2283 code indicates a problem with the injector control pressure (ICP) sensor circuit, which monitors high-pressure oil in the fuel injection system, common in diesel engines. The PCM detects a voltage or signal out of range, often due to wiring issues, sensor failure, or low oil pressure. This can cause poor engine performance, hard starting, or stalling.
01. Most Common Causes
- Faulty injector control pressure sensor
- Wiring or connector issues (shorts, opens, corrosion)
- Low engine oil level or pressure
- PCM software or hardware failure
02. Symptoms You Will Notice
- Check Engine Light on
- Hard starting or no start
- Rough idle or misfire
- Reduced engine power or stalling
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect ICP sensor connector and wiring for damage or corrosion.
Step 3: Test ICP sensor signal voltage with a multimeter (typically 0.5-4.5V at idle).
Step 4: Check engine oil level and pressure; repair as needed.
Step 5: If sensor and wiring are OK, replace the ICP sensor and clear codes.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended. The vehicle may experience stalling, reduced power, or difficulty starting, which can be dangerous in traffic.
How much does it cost to fix?▼
Typically $50-$150 for a sensor replacement, plus diagnostic time. Labor may add $100-$200 depending on the shop.
