This is one of the most frequent OBD2 trouble codes. Read the full article below to know what it means, how to fix it, and what other codes may show related to it.
P2015 is an OBD-II Code that refers to Intake Manifold Runner Position Sensor/Switch Circuit Range/Performance Bank 1
A P2015 code is a diagnostic trouble code that occurs with fuel injected engines from most manufacturers since 2003 such as Ford, Dodge, Toyota, Mercedes, Volkswagen, Nissan and Infiniti. It indicates the bank 1 intake manifold runner position sensor is out of range. If a fault or malfunction occurs, the program enters failsafe mode, in which it continues to function normally until the source of the problem is discovered and resolved.
When the ECU detects a shift in performance that is out of range, it sets the DTC P2015.
Common causes for this code include:
- Bad Intake Manifold Position Sensor
- Problematic IMRC actuator/solenoid
- Damaged wires or poor connections/Circuit issues
- Malfunctioning PCM
The symptoms of a P2015 code are:
- Illuminated Check Engine Light
- Rough idle
- Surge in engine
- Poor fuel economy
- Slight loss of low-end torque
- Engine misfires that are rare
To diagnose a P2015 DTC code, a technician would:
- Scan for codes in the ECM and look at the freeze frame data for failure.
- Visually inspect all harnesses and connectors that lead to and from the IAT sensor.
- Check for any loose, damaged, corroded, or disconnected wiring.
- Inspect the intake manifold for any damage.
- With a multimeter, test the voltage, resistance, and ground circuits of the IAT sensor. If everything checks out okay with the sensor itself and its circuit, then the issue may be with the PCM.
The following are some of the most common mistakes that a technician may make when diagnosing a P2015 code:
- Not thoroughly inspecting all the wiring and connectors for damage.
- Not checking the intake manifold for any damage.
- Not testing the IAT sensor with a multimeter.
- Failing to check for any loose, damaged, corroded, or disconnected wiring.
How serious is this?
A P2015 code is a serious code because it can lead to engine damage if not repaired.
What repairs can fix the code?
The following are solutions that may fix this problem:
- Replacing the intake manifold runner position sensor bank 1
- Repair or replacement of the wiring harness
- Fixing any electrical connection issues
- Restoring the intake manifold runner to proper movement
- Flashing or replacing PCM
A P2015 is related to and may be accompanied by the following codes:
P2119 - Throttle Body Control Module (TBCM) Relay Coil Circuit Open
P2118 - Throttle Body Control Module (TBCM) Relay Circuit High Voltage
In conclusion, the P2015 code is a diagnostic trouble code that refers to a problem with the intake manifold runner position sensor on bank 1. This code can be caused by a few different things such as a bad sensor, a problem with the wiring, or an issue with the PCM. If you have this code, it is important to get it fixed as soon as possible as it can lead to engine damage if not repaired.
