What Does P1217 Mean?
P1217 indicates that Injection Control Pressure (ICP) was not detected during engine cranking. This is functionally similar to P1212 and means the HEUI system failed to build any measurable oil pressure while the starter was cranking the engine. Without ICP, the hydraulic injectors cannot fire, and the engine will not start.
Safety Warning
The vehicle will not start or will stall immediately after starting. This creates a stranding hazard and prevents the vehicle from being driven. If the condition is intermittent, unexpected stalling in traffic is a serious safety concern.
Common Causes
25%
High-pressure oil pump failure or complete loss of pump output
25%
Catastrophic high-pressure oil system leak from multiple failed O-rings
20%
ICP sensor completely failed or disconnected, providing no signal
15%
Engine oil critically low or completely drained preventing pump priming
15%
IPR valve stuck fully open, dumping all pressure back to sump
Diagnostic Steps
1
Check engine oil level and condition immediately. A low or empty oil level is the simplest and most critical cause to rule out first.
2
Monitor ICP sensor voltage during cranking. A functional sensor should show at least some voltage change during cranking even if pressure is low.
3
Inspect the ICP sensor connection and test the sensor with a known-good replacement to rule out a dead sensor.
4
Command the IPR valve to its maximum closed position and attempt to crank, monitoring for any ICP buildup. A stuck-open IPR prevents all pressure generation.
5
If oil is full and IPR responds, check the high-pressure oil pump for drive gear failure or internal seizure by inspecting pump output.
6
Perform a systematic leak-down test of the high-pressure oil system including stand pipes, branch tubes, dummy plugs, and injector bore O-rings.

The most common cause of P1217 (Injector Control Pressure Not Detected During Crank) is: High-pressure oil pump failure or complete loss of pump output
Typical repair costs for P1217 range from $500 to $3,500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
