How do I fix code P2088 SUZUKI?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Cost of diagnosing the P2088 SUZUKI code
The cost of diagnosing the P2088 SUZUKI code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P2088 SUZUKI Description
The Camshaft Position (CMP) Actuator system enables the Engine Control Module (ECM) to change the timing of the camshafts while the engine is operating. The CMP actuator solenoid signal from the ECM is Pulse Width Modulated (PWM). The ECM controls the CMP actuator solenoid duty cycle by controlling the amount of solenoid ON time. The CMP actuator solenoid controls the advance or the retard of each camshaft. The CMP actuator solenoid controls the oil flow that applies the pressure to advance or retard the camshafts.
Ignition voltage is supplied directly to the CMP actuator solenoid. The ECM controls the solenoid by grounding the control circuit with a solid-state device called a driver. The driver is equipped with a feedback circuit that is pulled-up to a voltage. The ECM can determine if the control circuit is open, shorted to ground, or shorted to a voltage by monitoring the feedback voltage.
The Diagnostic Trouble Code (DTC) will set if the ECM detects a short to ground in the CMP actuator solenoid circuits for more than 4 seconds or a cumulative of 50 seconds, when the solenoid is commanded OFF.
