P1151 Diagnostic Trouble Code (12 interpretations)
12 manufacturer-specific interpretations across 11 manufacturers in the TuningBot DTC database.
Chrysler
1 interpretation
Dodge
1 interpretationThe control module detected that the actual Fuel Rail Pressure Malfunction Maximum value stayed above the specified value (positive control deviation). This is the manufacturer-specific definition used by Dodge.
Ford
1 interpretationThe control module detected a fault associated with the Lack of Upstream Heated Oxygen Sensor Switch Sensor Indicates Lean Bank 2 circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Ford.
Possible causes
- Wiring
- intake/fuel system
- HO2S
- EGR system
- oil level
- camshaft timing
Recommended checks
- Perform a full module scan
- Review freeze-frame and occurrence data
- Compare commanded and measured values
- Check applicable OEM service information
Jeep
1 interpretationThe control module detected that the actual Fuel Rail Pressure Malfunction Maximum value stayed above the specified value (positive control deviation). This is the manufacturer-specific definition used by Jeep.
Kia
1 interpretationThe control module detected improper operation of the Accelerator pedal position (APP) circuit. This is the manufacturer-specific definition used by Kia.
Possible causes
- Wiring
- APP sensor
- ECM
Land Rover
1 interpretationThe control module detected that the air-fuel mixture stayed leaner than the target despite full corrective control (Heated oxygen sensor (HO2S), upstream, bank 2 - mixture). This is the manufacturer-specific definition used by Land Rover.
Possible causes
- Intake leak
- fuel pressure low
- injector(s) blocked
- HO2S
- ECM
MINI
1 interpretationThe control module detected a fault associated with the O2 Sensor Heater Circuit Signal Intermittent Bank 2 Sensor 1 circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by MINI.
PSA
1 interpretationThe control module detected a short circuit to battery voltage in the Motorised throttle control circuit. Documented for the Magneti Marelli MM6KP engine ECU (EW7A/EW10A) on Peugeot applications; the same PSA control units are also fitted to Citroën models.
Suzuki
1 interpretationThe control module detected that the Heated oxygen sensor (HO2S) 1, bank 2 - output voltage stayed above the expected range. This is the manufacturer-specific definition used by Suzuki.
Possible causes
- Wiring short to positive
- HO2S
- ECM
VAG
2 interpretationsThe control module detected a fault associated with the Long term fuel trim 1, Bank 1 - below lean limit circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Audi.
Possible causes
- Fuel pressure/pump
- injectors
- intake/exhaust leak
- HO2S
The control module detected that the air-fuel mixture stayed leaner than the target despite full corrective control (Long Term Fuel Trim Additive Air; Bank 1; Range 1: System). This is the manufacturer-specific definition used by Volkswagen. Volkswagen Group tools also report it as fault code 17559. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).
Symptoms
Malfunction Indicator Lamp (MIL) active
Possible causes
- Intake System faulty/leaking
- Fuel Pressure, Fuel Pressure Regulator and Fuel Pump faulty
- Fuel Injectors faulty/leaking
- Exhaust System faulty/leaking
- Activated-Charcoal Filter/System faulty/leaking
- Secondary Air Injection System faulty/leaking
Recommended checks
- Check Intake System for Leaks
- Check Fuel Pressure, Fuel Pressure Regulator and Fuel Pump
- Check Fuel Injectors
- Check Exhaust System for Leaks
- Check Activated-Charcoal Filter/System
Volvo
1 interpretationThe control module detected improper operation of the Heated oxygen sensor (HO2S) 1, bank 2. This is the manufacturer-specific definition used by Volvo.
Possible causes
- Wiring
- HO2S
- ECM
