What Does P069F Mean?
The PCM has detected a fault in the throttle actuator control (TAC) warning lamp circuit. This lamp, often called the electronic throttle control (ETC) indicator or "lightning bolt" warning, alerts the driver to throttle-by-wire system faults. This code specifically indicates the lamp circuit itself has a problem — the lamp may not illuminate when it should, or the PCM cannot verify the lamp driver. This is a secondary fault; the primary throttle issue may already exist but the warning lamp cannot alert the driver.
Common Causes
30%
Burned-out throttle actuator control warning lamp bulb or failed LED in the instrument cluster
25%
Open or short in the wiring between PCM and instrument cluster for the TAC lamp circuit
20%
Failed instrument cluster lamp driver or internal cluster fault
15%
Poor connection at the PCM or instrument cluster connector affecting the lamp circuit
10%
PCM internal lamp driver circuit failure
Diagnostic Steps
1
Perform a key-on bulb check; with key on/engine off, the TAC/ETC warning lamp should illuminate for 2-3 seconds. If it does not illuminate during the bulb check, the circuit fault is confirmed.
2
Access the instrument cluster connector and measure voltage on the TAC lamp circuit pin with the PCM commanding the lamp on; battery voltage or ground should be present depending on the circuit design.
3
Check for communication DTCs between the PCM and instrument cluster, as many modern vehicles control the warning lamp via CAN bus rather than a discrete wire.
4
If a discrete lamp circuit, check wiring continuity between the PCM output pin and the instrument cluster lamp pin; should read near 0 ohms.
5
If the cluster uses CAN-controlled lamps, verify CAN bus communication is functional between the PCM and body control module/instrument cluster.

The most common cause of P069F (Throttle Actuator Control Lamp Control Circuit) is: Burned-out throttle actuator control warning lamp bulb or failed LED in the instrument cluster
Typical repair costs for P069F range from $75 to $500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The vehicle may be driveable, but the risk is that the throttle warning lamp cannot illuminate during a real throttle system fault. This means the driver would not receive visual warning of a potentially dangerous throttle malfunction. Repair is important as a safety precaution even though current driveability may be unaffected.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P069F to identify the root cause.
