P2107 — Throttle Actuator Control Module Processor

OBD2 code P2107 flags a problem with the throttle and intake air metering (throttle actuator control module processor). Short, gentle driving to a shop is usually possible. Common culprits: contaminated or failed MAF/MAP sensor, intake air leaks after the MAF sensor, wiring or connector faults in the throttle circuit.

powertrain (engine/transmission)

Is it safe to drive?

Drive with caution Drive with caution. Many throttle faults put the car into limp mode with limited power — enough to reach a shop, not for highway trips. If the engine stalls or the pedal stops responding, do not drive.

How to diagnose with an OBD scanner

  1. Read the code and freeze frame Connect an OBD2 scanner, confirm P2107 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
  2. 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 P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
  3. Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the throttle and intake air metering for damage, corrosion, chafing or poor contact.
  4. Subsystem check Inspect and clean the throttle body; check that the plate moves freely.
  5. Subsystem check Watch throttle position and MAF/MAP readings in live data while pressing the pedal — values should change smoothly.
  6. Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2107 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P2107 (parts and labor, USD, independent shop rates): Clean the throttle body: $80–$200; Replace the MAF or MAP sensor: $150–$400; Replace the throttle body assembly: $250–$700. Overall, fixing P2107 usually costs between $80 and $700. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.

Common questions

Is it safe to drive with P2107?

Drive with caution. Many throttle faults put the car into limp mode with limited power — enough to reach a shop, not for highway trips. If the engine stalls or the pedal stops responding, do not drive.

How do I diagnose P2107 myself?

Start with a scan: confirm P2107, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the throttle and intake air metering, and verify the suspect component against live data before buying parts.

What is the most common cause of P2107?

The most common causes are: contaminated or failed MAF/MAP sensor, intake air leaks after the MAF sensor, wiring or connector faults in the throttle circuit.

How much does it cost to fix P2107?

Clean the throttle body — $80–$200; Replace the MAF or MAP sensor — $150–$400; Replace the throttle body assembly — $250–$700. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.

What does OBD2 code P2107 mean?

OBD2 code P2107 flags a problem with the throttle and intake air metering (throttle actuator control module processor). Short, gentle driving to a shop is usually possible. Common culprits: contaminated or failed MAF/MAP sensor, intake air leaks after the MAF sensor, wiring or connector faults in the throttle circuit.

What does P2107 mean?

When P2107 appears on a scan, it means the control module has flagged a problem in the throttle and intake air metering: throttle actuator control module processor. The fault sits in the powertrain (engine/transmission) group of the OBD2 standard.

To set P2107, the control module compares live readings of the throttle and intake air metering against calibrated limits, usually over several drive cycles. Alongside the code it stores a freeze frame — a snapshot of rpm, load, coolant temperature and vehicle speed at the moment of failure. Reading that snapshot first saves diagnostic time.

Common symptoms of P2107

  • Check Engine Light on
  • limp-home mode with reduced power
  • poor throttle response
  • stalling when coming to a stop
  • unstable or high idle

What causes P2107?

  • dirty throttle body or stuck throttle plate
  • intake air leaks after the MAF sensor
  • contaminated or failed MAF/MAP sensor
  • wiring or connector faults in the throttle circuit
  • faulty throttle position sensor or pedal sensor
