P2015
Intake Manifold Runner Position Sensor/Switch Circuit Range/Performance (Bank 1)
If your code reader dashboard displays the generic DTC error code P2015, your vehicle is currently experiencing an active failure related to "Intake Manifold Runner Position Sensor/Switch Circuit Range/Performance (Bank 1)". Proper system troubleshooting is required to safely clear this warning.
Driver's Summary
When your OBD2 scanner shows P2015, the engine control module has flagged an issue specifically related to intake manifold runner position sensor/switch circuit range/performance (bank 1). Typical symptoms include check engine light, minor drivability issues, hesitation. You can typically drive short distances, but ignoring this code long-term will cause accelerated component wear and higher repair costs.
Symptoms
Check engine light, minor drivability issues, hesitation
Common Causes
- Worn plastic intake manifold mechanism (common on VW/Audi)
- Faulty runner position sensor
- Carbon buildup
- Actuator motor failure
How to Fix
- 1 Install aluminum bracket fix (if applicable)
- 2 Replace position sensor
- 3 Replace intake manifold assembly
- 4 Clean carbon deposits
Technical Explanation
Code P2015 is confirmed when the ECM's diagnostic algorithm detects a parameter deviation that persists across a defined number of consecutive drive cycles. The PCM distinguishes between electrical faults (circuit codes) and performance faults (rationality codes) by comparing the sensor's reported value against what other sensors would predict under the same engine operating conditions. The MIL illuminates after the fault is confirmed on two consecutive drive cycles, and the freeze frame data captured at first detection is stored in the PCM's memory for diagnostic reference.
Is It Safe to Drive?
Medium-severity fault: the car functions but not optimally. The worn plastic intake manifold mechanism (common on vw/audi) issue will not resolve itself and will cause measurable long-term wear. A repair in the $50–$900 range now avoids far higher costs later.
Mechanic's Pro Tip
The most common mistake with P2015 is replacing the sensor without verifying the reference voltage and ground integrity first. Use a scan tool to monitor the sensor's live output; a truly failed sensor shows a stuck, flatlined reading — a sensor that fluctuates but reads slightly off usually indicates a wiring or vacuum issue, not a dead sensor. Always spray electrical contact cleaner on the connector pins before condemning the sensor.
Bracket fix kit: $50 - $150; Manifold replacement: $600 - $900
