The engine warning light came on during a motorway drive. The driver noticed no loss of power, no smoke, and the car starts normally.
Fault codes
| Code | Description | Status |
|---|---|---|
| P2015 | Intake Manifold Runner Position Sensor/Switch Circuit Range/Performance (Bank 1) | Confirmed |
Measurements and live data
| Parameter / measurement | Measured | Expected |
|---|---|---|
| Intake flap position, specified / actual | 0 % / 38 % | actual follows specified |
Tests performed
- Actuator test with a scan toolThe actuator arm moves through its full travel, the flap shaft does not follow
- Flap shaft turned by handTurns freely, no soot seizure
- Visual check of the linkagePlastic ball joint between actuator arm and flap shaft broken
Solution
Root cause
Broken plastic ball joint in the intake manifold flap linkage.
Repair
Fitted a metal repair link between the actuator and the flap shaft, cleared the code and repeated the actuator test: specified and actual position now match. The flaps moved freely, so the manifold did not need replacing.
Parts
Intake flap linkage repair kit
Labour time
0.5 h
Lesson learned
Turn the flap shaft by hand before ordering a manifold: a seized shaft needs the manifold, a broken link only needs a repair kit.
Training case: the usual fix for this fault, not a confirmed repair on a specific car.
