C1016 — Pedal Angle to Pedal Feel Simulator Cut-off Pressure Comparison
OBD2 code C1016 flags a problem with the sensor and actuator circuits (C1016 — pedal angle to pedal feel simulator cut-off pressure comparison: causes, symptoms & fix). The car is usually drivable while you plan the repair. Common culprits: corroded, loose or damaged connector, control module driver fault, poor ground connection.

Is it safe to drive?
Short-term driving is OK In most cases the car remains drivable, possibly with reduced performance or a disabled auxiliary system. If symptoms include stalling, no-start or brake/steering warnings, treat it as urgent.
How to diagnose with an OBD scanner
- Read the code and freeze frame Connect an OBD2 scanner, confirm C1016 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
- Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many C0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
- Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the sensor and actuator circuits for damage, corrosion, chafing or poor contact.
- Subsystem check Measure reference voltage, ground and signal continuity at the component connector.
- Subsystem check Wiggle-test the harness while watching the signal in live data — dropouts reveal broken wires.
- Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm C1016 does not return.
Approximate repair cost
Repair cost depends on which component actually failed. Typical scenarios for C1016 (parts and labor, USD, independent shop rates): Repair wiring or connectors: $80–$250; Replace the faulty sensor or actuator: $150–$500; Control module repair: $300–$1,000. Overall, fixing C1016 usually costs between $80 and $1,000. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.
Common questions
What does OBD2 code C1016 mean?
OBD2 code C1016 flags a problem with the sensor and actuator circuits (C1016 — pedal angle to pedal feel simulator cut-off pressure comparison: causes, symptoms & fix). The car is usually drivable while you plan the repair. Common culprits: corroded, loose or damaged connector, control module driver fault, poor ground connection.
What is the most common cause of C1016?
The most common causes are: corroded, loose or damaged connector, control module driver fault, poor ground connection.
Will C1016 clear itself?
Sometimes C1016 clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.
Is it safe to drive with C1016?
In most cases the car remains drivable, possibly with reduced performance or a disabled auxiliary system. If symptoms include stalling, no-start or brake/steering warnings, treat it as urgent.
How do I diagnose C1016 myself?
Start with a scan: confirm C1016, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the sensor and actuator circuits, and verify the suspect component against live data before buying parts.
C1016 — C1016 — Pedal Angle to Pedal Feel Simulator Cut-off Pressure Comparison: Causes, Symptoms & Fix
When the engine control unit detects a mismatch between what the accelerator pedal position sensor reports and what the brake system pressure switch expects, it logs trouble code C1016. The code specifically refers to a comparison between pedal angle and pedal feel simulator cut-off pressure—a safety-related check that validates proper operation of the drivability controls. The module continuously compares live sensor data against factory-calibrated thresholds, and if the readings fall outside acceptable ranges over multiple drive cycles, C1016 becomes stored.
The system at the heart of this code monitors two linked signals: the pedal position sensor tells the ECU how far the accelerator is depressed, while the pedal feel simulator pressure switch confirms that the brake circuit responds appropriately to driver input. These components work together to prevent conflicting commands between acceleration and braking. When either signal behaves erratically, drops out completely, or reads a value the module cannot reconcile with expected pressure relationships, C1016 triggers. The ECU also captures a freeze frame snapshot—engine RPM, load, coolant temperature, and vehicle speed captured at the moment of failure—which proves invaluable during diagnosis.
Symptoms of C1016
- The vehicle may enter limp-home mode, limiting power output and speed
- The affected circuit operates intermittently or ceases to function entirely
- The Check Engine Light or Malfunction Indicator Lamp illuminates on the dash
- Some drivers notice increased fuel consumption due to improper throttle mapping
- Acceleration may feel sluggish or unresponsive when the pedal is pressed
- In rare cases, brake system warning indicators may accompany the code
Common Causes
- Damaged, corroded, or loose wiring in the pedal position sensor or pressure switch circuit — by far the most frequent culprit
- Faulty accelerator pedal position sensor or brake pressure switch
- Poor ground connection at the sensor or control module
- Blown fuse feeding the affected circuit
- Failed driver circuit inside the ECU or body control module
Diagnosing C1016
- Connect an OBD2 scanner and confirm C1016 is stored. Record the associated freeze frame data — it reveals engine conditions when the fault first appeared.
- Pull any related trouble codes present at the same time. Cross-reference these with manufacturer TSB databases for known fixes or software updates applicable to your vehicle.
- Perform a thorough visual inspection of the wiring harness and connectors serving the pedal sensor and pressure switch. Look for frayed insulation, water intrusion, corrosion, or connectors that are not fully seated.
- With the key on and engine off, verify reference voltage, ground integrity, and signal wire continuity at the component connector using a multimeter.
- While monitoring live data on the scanner, gently wiggle the harness and connectors. Any signal dropouts or erratic readings point to broken wires hidden inside the insulation.
- Clear C1016 and complete a drive cycle that reproduces the freeze frame conditions (same speed, load, and temperature). Verify the code does not reappear.
Repair Options and Costs
- Wiring repair or connector replacement: $80–$250 — the most common and economical fix
- Replace faulty sensor or actuator: $150–$500 — sensor replacement is straightforward on most models
- Control module diagnosis and repair: $300–$1,000 — rarely necessary but required if driver circuitry is compromised
Total Repair Cost
Depending on which component actually failed, C1016 repairs typically range from $80 to $1,000. Wiring issues resolve at the lower end of that spectrum, while module-level repairs reach the upper limit. Diagnosing the root cause before purchasing parts prevents wasteful spending — the control module is rarely the source despite being the most expensive component to address.
Can You Drive With C1016?
In most instances the vehicle remains driveable, though you may experience reduced performance or a disabled auxiliary system. Treat the code as urgent if it is accompanied by stalling, failure to start, or brake/steering warnings — these indicate a safety-critical fault requiring immediate attention.
