Causes
- Open or short in valve wiring harness
- Poor or corroded connector/terminal at the flow level control valve
- Faulty flow level control valve (stuck, mechanically seized or internally shorted)
- Insufficient or contaminated hydraulic/fluid supply (blockage)
- Faulty body/chassis control module (ECU) or drive output
- Intermittent wiring fault (pinched/damaged)
Symptoms
- Related system warning light(s) illuminated (may vary by model)
- System operation degraded or in limp/limited mode for affected system
- Unusual noises from valve area when system commands operation
- Intermittent or permanent loss of the function controlled by the valve
- No response during active tests
What to check
- Read freeze frame and full scan-tool data; note MIL status and any related codes
- Perform active command (bi-directional test) of the flow level control valve with a scan tool
- Visual inspect connector and wiring for damage, corrosion, loose pins or water entry
- Backprobe harness to confirm supply voltage and ground while commanding valve
- Measure valve solenoid coil resistance per service manual
- Check for fluid contamination or blockage in the valve or lines (if applicable)
Signal parameters
- Control signal: typically PWM duty control from module (0–100% duty) when commanded
- Command voltage: 0 V (off) to near battery voltage when driven — verify with scan tool/oscilloscope
- Expected coil resistance: consult Hyundai service manual for exact ohms (measure for open/short)
- Signal response: when commanded on, valve current should change and actuator position/flow should respond
- No signal or fixed voltage indicates wiring or module fault; erratic PWM indicates module or wiring intermittent
Diagnostic algorithm
- Retrieve DTCs and freeze-frame data; note any related codes that may help diagnosis.
- Perform an active test (command valve ON/OFF) using factory scan tool and observe system response and live data.
- Visually inspect the valve, connector and wiring harness for corrosion, damage, chafing or water ingress. Repair as needed.
- With ignition ON, backprobe the valve connector. Verify battery supply voltage at the power pin and a good ground at the ground pin.
- Command the valve while monitoring voltage/current. Confirm the control signal (PWM/voltage) changes when commanded.
- Measure the valve coil resistance and compare to service manual; replace valve if open/short or out of specification.
- If electrical supply and valve are good but no operation, check continuity of control wiring back to the control module and test for shorts to battery/ground.
- If wiring and valve check good, suspect module output. Verify module operation by comparing commands to known-good circuits or consult service procedures for module bench tests.
- If valve mechanical (stuck/blocked) is suspected, inspect and clean/replace valve or related fluid lines per service instructions.
- After repairs, clear codes, perform active tests, and road test to confirm fault does not return.
Likely causes
- Corroded/loose connector at the valve
- Valve mechanically stuck or contaminated
- Broken or shorted harness to the valve
- Failed valve solenoid/actuator
- Faulty control module driving the valve (less common)
