Injector Control Pressure Erratic
What does P2292 mean?
The P2292 code means the vehicle's onboard diagnostic system has detected: Injector Control Pressure Erratic. This is a moderate severity code.
Common Symptoms
- Engine surging at idle
- Inconsistent power delivery
- Check Engine Light illuminated
- Rough idle that comes and goes
- Stalling at low RPM
Probable Causes (Ranked by Likelihood)
- ICP sensor intermittent failure Very High
- IPR valve sticking intermittently High
- High-pressure oil leak that varies with temperature Moderate
- Damaged ICP sensor wiring or connector Moderate
Step-by-Step Diagnostic Procedure
-
Monitor ICP sensor readings for erratic pressure swings
-
Check ICP sensor connector for oil contamination (blown sensor diaphragm)
-
Inspect ICP sensor wiring for chafing or damage
-
Test IPR valve duty cycle response with a scan tool
-
Compare ICP readings at cold start versus hot restart
Frequently Asked Questions
Can I drive with code P2292?
Short distances only. Erratic pressure can cause stalling without warning. Avoid heavy loads and highway driving until repaired.
What causes P2292?
Commonly an ICP sensor that is failing intermittently or has oil contamination in its connector from a blown internal diaphragm.
Is P2292 expensive to fix?
Costs range from $150 for an ICP sensor to $1200 for IPR valve and high-pressure oil system repairs. Start with the sensor as it is the most common fix.
