What Does P1167 Mean?
This code indicates the on-board diagnostic system attempted to run a self-test procedure that requires the driver to press the throttle, but the throttle was not depressed during the test window. This is a procedural or test execution fault rather than a component failure. The code is typically set during a Key-On Engine Running (KOER) self-test sequence when the technician fails to follow the test instructions properly.
Common Causes
40%
Technician did not depress the throttle when prompted during the self-test procedure
20%
Throttle position sensor (TPS) not registering pedal input due to misadjustment
15%
Failed or disconnected accelerator pedal position (APP) sensor
15%
Electronic throttle body stuck or not responding to pedal input
10%
Communication fault between the APP sensor module and PCM
Diagnostic Steps
1
Clear the code and re-run the KOER self-test, following the exact procedure: when prompted (usually indicated by a brief engine RPM flare), quickly press and release the accelerator pedal to wide-open throttle.
2
Monitor the throttle position sensor percentage in live data while pressing the accelerator; verify it smoothly moves from 0% to near 100%.
3
If the TPS does not register pedal input, check the accelerator pedal position sensor connector and wiring for faults.
4
Inspect the electronic throttle body for binding or sticking; verify it responds to pedal input by observing throttle blade movement.

The most common cause of P1167 (Invalid Test,throttle not depressed) is: Technician did not depress the throttle when prompted during the self-test procedure
Typical repair costs for P1167 range from $0 to $150, depending on the vehicle, location, and whether you do it yourself or go to a shop.
No safety implications from this code itself. It simply indicates an incomplete diagnostic test. If the underlying cause is a faulty TPS or APP sensor, those should be addressed as they can affect throttle response.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1167 to identify the root cause.
