Injector/Injection Timing Control Circuit Malfunction Engine performance degradation, rough idle, reduced power, possible stalling

AutoFixDB - Free OBD-II diagnostic trouble code lookup. Find causes, symptoms, diagnostic steps and repair solutions.

Overview

OBD-II code P0216 indicates a malfunction in the injector or injection timing control circuit affecting fuel injection timing control, potentially due to wiring issues, sensor faults, timing pump problems, or ECU control faults

Common Symptoms

Check Engine Light illuminated
Rough or uneven idle
Decreased engine power or acceleration
Intermittent misfires or hesitation
Hard starting or stalling

Most Common Causes

Faulty injection timing control circuit or solenoid high

ECU detects timing signal outside specifications due to internal circuit or timing controller failure

Damaged or corroded wiring/connectors related to injection timing circuit high

Poor electrical connections can distort control signals and trigger P0216

Crankshaft or camshaft position sensor malfunction medium

Incorrect sensor signals can mislead ECU timing control

Fuel delivery issues (e.g., low fuel pressure, clogged filter, bad pump) medium

Fuel delivery faults can mimic injection timing errors

ECM/PCM internal malfunction or software issue low

Rare but possible if ECU misinterprets timing due to firmware or hardware failure

Diagnostic Steps

Connect OBD-II scanner and retrieve codes including freeze‑frame data

Expected: P0216 stored with possible related codes

Interpretation: Confirms baseline and context for injection timing fault
Visually inspect wiring and connectors for corrosion, damage, or loose connections

Expected: No broken wires or corroded terminals

Interpretation: Eliminates common electrical faults
Test injector timing control solenoid or driver circuit with multimeter per OEM specs

Expected: Resistance/operation within specification

Interpretation: Identifies failed solenoid or driver circuit
Inspect crankshaft/camshaft position sensors and verify signals

Expected: Accurate sensor signals at ECU

Interpretation: Determines if sensor errors are influencing timing control
Check mechanical timing (timing chain/belt alignment) and fuel pressure

Expected: Correct mechanical timing and adequate fuel pressure

Interpretation: Ensures no underlying mechanical cause

Repair Solutions

Repair or replace damaged wiring/connectors medium

Estimated Cost: $100 - $300

Typical for harness or connector issues

Replace injection timing control solenoid or module medium

Estimated Cost: $200 - $600

Cost varies by vehicle make and part

Replace crankshaft or camshaft position sensor easy

Estimated Cost: $150 - $400

Sensor faults often trigger timing errors

Correct mechanical timing (belt/chain) or fuel delivery issues hard

Estimated Cost: $300 - $1200

More complex repairs when mechanical timing is off

ECM reprogramming or replacement hard

Estimated Cost: $500 - $1500

High cost and low frequency; only after other causes eliminated

Common Misdiagnoses

Avoid these common diagnostic mistakes:

Assuming faulty injectors without testing control circuit
Attributing trouble solely to ECM failure without sensor/circuit verification

Frequently Asked Questions
