Fix P0216: Injection Timing Control Circuit Range/Performance – Trust iCarsoft CR Eagle
Few things are more frustrating than a check engine light that signals a critical powertrain issue—especially when it’s tied to OBD2 code P0216. This code points to a problem with your vehicle’s injection timing control circuit, and ignoring it can lead to severe engine damage, reduced performance, or even complete breakdowns. But with the right knowledge and a reliable diagnostic tool, you can identify the root cause, make the fix, and get back on the road with confidence.
What Is OBD2 Code P0216?
First, let’s decode the basics. OBD2 (On-Board Diagnostics II) codes are standardized across all modern vehicles (1996 and newer in the U.S., 2001 and newer in the EU) to communicate issues with key systems. P0216 falls under the “powertrain” category, meaning it affects components that generate or deliver engine power.
The official definition of P0216 is: “Injection Timing Control Circuit Range/Performance”. Let’s break this down to eliminate confusion:
-
Injection Timing: The precise moment fuel is injected into the engine’s cylinders—critical for optimal combustion, fuel efficiency, and engine power. Even small timing errors cause rough running, misfires, or overheating.
-
Control Circuit: The electrical pathway connecting the fuel injection system to the Engine Control Module (ECU), including wiring, sensors, and solenoids that regulate injection timing.
-
Range/Performance: The ECU is receiving signals from the circuit that fall outside normal operating ranges, leading to inaccurate or inconsistent injection timing.
In short, P0216 tells you that your vehicle’s ECU can’t properly control fuel injection timing due to a faulty circuit. This issue is most common in diesel engines (which rely heavily on precise injection timing) but can also occur in some gasoline vehicles with direct injection systems.
Common Symptoms of P0216
P0216 rarely goes unnoticed—most drivers will experience one or more of the following symptoms, ranging from mild to severe:
-
Illuminated Check Engine Light (MIL): Solid for most cases; flashing indicates a severe issue requiring immediate attention.
-
Reduced Engine Power: ECU triggers “limp mode” to protect the engine, limiting speed and acceleration.
-
Rough Idle or Misfires: Improper injection timing disrupts combustion, causing engine shaking or uneven running at idle.
-
Increased Fuel Consumption: Poor combustion efficiency leads to wasted fuel and lower miles per gallon (MPG).
-
Engine Overheating: Incomplete combustion generates excess heat, raising engine temperature beyond safe levels.
-
Hard Starting: Especially in diesel vehicles—incorrect timing makes engine ignition harder, leading to prolonged cranking.
-
Stalling: Severe cases cause unexpected engine shutdown while driving, posing a safety risk.
If you notice any of these symptoms, scan your vehicle for codes immediately. Addressing P0216 early prevents costly repairs to the engine, fuel injectors, or ECU.
What Causes OBD2 Code P0216?
To fix P0216 effectively, pinpoint the root cause first. Below are the most common triggers, ordered by frequency:
Faulty Injection Timing Sensor
Crankshaft/camshaft position sensors send erratic/inaccurate signals to the ECU, triggering P0216. Signs include intermittent symptoms or recurring codes post-clearing.
Damaged or Frayed Wiring
Wiring near engine/exhaust is vulnerable to heat, vibration, or fluids—frayed wires, short circuits, or corrosion disrupt electrical signals.
Malfunctioning Fuel Injection Pump (Diesel)
Worn/faulty pumps fail to maintain consistent injection timing, accompanied by reduced power or hard starting.
Clogged or Faulty Fuel Injectors
Carbon deposits or leaks prevent injectors from opening/closing properly, causing inconsistent fuel delivery and timing issues.
Faulty Engine Control Module (ECU)
Rare cause—software glitches, voltage spikes, or internal damage prevent the ECU from processing sensor signals correctly.
Low or Contaminated Fuel
Poor-quality fuel or contamination (water/dirt) damages injectors; low fuel pressure (faulty pump/filter) also triggers P0216.

Step-by-Step Guide to Fixing P0216 with the iCarsoft CR Eagle
Step 1: Connect the CR Eagle to Your Vehicle
Plug the CR Eagle’s OBDII connector into the port (under driver’s dashboard), turn on ignition (ACC/ON mode), and power on the tool—it auto-connects to the ECU.
Step 2: Read DTCs and Freeze Frame Data
Select “Diagnostics” > “Engine” > “Read DTCs” to retrieve P0216 + related codes. View “Freeze Frame” to see conditions when the code triggered (speed, RPM, temp).
Step 3: Clear the Code and Test-Drive
Select “Clear DTCs” to erase P0216, then test-drive (focus on trigger conditions: acceleration, highway driving). Re-scan—if P0216 returns, proceed to diagnosis.
Step 4: Monitor Live Data
Select “Live Data” > “Engine” > “Injection Timing” to monitor sensor voltage (stable 0.5–4.5V typical) and fuel pressure. Look for consistent values that adjust with engine load.
Step 5: Perform Bi-Directional Testing
Select “Bi-Directional Control” > “Injection Timing Test” to activate sensors/injectors. Non-responsive sensors need replacement; faulty injectors require cleaning/replacement.
Step 6: Inspect Wiring and Connectors
Check injection timing sensor wiring for fraying/corrosion (repair/replace as needed). Clean connectors with electrical contact cleaner and reconnect firmly.
Step 7: Address Fuel System Issues
Check fuel pressure via live data (low pressure = faulty pump/filter). Clean/replace clogged/leaking injectors; refuel with high-quality fuel to rule out contamination.
Step 8: Clear Codes and Verify the Fix
Clear DTCs post-repair, take a 20–30 minute test-drive, and re-scan. If no codes appear, the fix is successful!
FAQs: Your P0216 Questions Answered
Can I drive with code P0216?
Short trips (e.g., to the auto parts store) may be safe, but prolonged driving is not recommended. P0216 can lead to engine overheating, misfires, or permanent damage. If the check engine light is flashing, stop driving immediately—this indicates a severe issue that could cause catastrophic engine failure.
How much does it cost to fix P0216?
Costs vary by cause:
-
Injection timing sensor: $80–$200 (part only; labor adds $50–$150).
-
Fuel injectors: $150–$400 per injector (plus labor).
-
Fuel injection pump (diesel): $500–$1,500 (part + labor).
-
Wiring/connector repairs: $50–$150.
Using the CR Eagle to diagnose yourself saves $80–$150 in mechanic diagnostic fees.
