Intake Manifold Pressure Sensor (Part No. 12615223) Key benefits Restores accurate manifold pressure readings so the engine control unit (ECU) can manage airfuel mixture and ignition timing correctly. Eliminates common drivability problems caused by a failing sensor, including rough idle, poor fuel economy, hesitation, and hard starting. Directfit replacement for vehicles requiring part number 12615223, providing a straightforward swap with no modification required. What this part does Measures absolute pressure inside the intake manifold and converts it into an electrical signal for the engine control system. Helps the ECU calculate load, fuel delivery, and ignition timing for consistent engine performance across operating conditions. Provides reliable data for turbocharged or naturally aspirated systems that depend on accurate manifold pressure information. Key attributes Part number: 12615223 Functionality: Intake manifold absolute pressure sensing (MAP) Compatibility: Intended as a replacement for applications that specify part number 12615223; confirm fitment with vehicle parts catalog or installer before Form factor: Compact sensor designed for mounting in the intake manifold area (designed for direct replacement in compatible vehicles) Performance: Provides stable, repeatable pressuretovoltage output for ECU control and diagnostics Why customers need it A defective intake manifold pressure sensor can trigger diagnostic trouble codes, reduce fuel efficiency, and negatively affect drivability. Replacing the sensor with one that matches part number 12615223 corrects the input the ECU relies on and restores normal engine behavior. Use cases / applications Replacement during routine diagnosis: Swap in part 12615223 when testing reveals incorrect manifold pressure readings or when the vehicle reports MAPrelated trouble codes. after mechanical or environmental damage: a sensor that has been contaminated, cracked, or otherwise compromised to prevent incorrect ECU inputs. Performance troubleshooting: Use a sensor to eliminate faulty MAP readings as the cause of turbo boost control or fuel trim issues. Installation and verification Designed for plugandplay replacement in vehicles that accept part number 12615223. Verify electrical connector and mounting match your vehicle before installation. After installation, clear any related diagnostic codes and perform a test drive or diagnostic scan to confirm proper operation and restored engine parameters. Notes Confirm compatibility with your vehicle's parts list or with a professional installer prior to using part number 12615223.
