Code Definition

P1288 — Intake manifold Short Runner Tuning Valve Solenoid circuit

System: Powertrain  |  Type: Manufacturer-Specific  |  Make: Chrysler

About P1288

P1288 is a manufacturer-specific powertrain diagnostic trouble code recorded for Chrysler vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P1288 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) in the monitored circuit.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

P1288 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

This fault code sets when the Powertrain Control Module (PCM) detects an electrical fault in the circuit controlling the intake manifold short runner tuning valve solenoid. This solenoid operates a valve that changes the effective length of the intake runners, allowing the engine to favour low speed torque or high speed power as conditions change. The PCM monitors the solenoid control circuit and sets this code for an open circuit, a short to ground or voltage, or a continuity problem. Symptoms can include reduced power or torque in part of the rev range, a slight loss of efficiency, and a che...
