P1037 Code - Cylinder 1 Oil Supply Solenoid Valve Driver Short To Ground
Quick Answer
Multi-Air is an electronically controlled variable intake valve phase and lift system. Common causes include Faulty Variable Valve Actuator (VVA) Solenoid, Variable Valve Actuator Solenoid harness is open or shorted, Variable Valve Actuator Solenoid circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1037 Description
The Multi-Air valve train has a mechanical camshaft lobe acting on a hydraulic pump located between the camshaft intake lobe and the intake valve. The pump provides oil under pressure to a two-way electro-hydraulic solenoid valve called the Variable Valve Actuator (VVA) Solenoid. The VVA Solenoid is electronically controlled during the specific intake cam lobe event by the Powertrain Control Module (PCM). During the event, the VVA Solenoid is commanded to either hold oil pressure or bleed oil. The Variable Valve Actuator (VVA) Solenoid is a normally open solenoid. The PCM provides 12 volts to close the solenoid. The position of the VVA Solenoid determines the intake valve timing and lift. This change on valve action is similar to creating a change in the camshaft lobe profile affecting the lift and duration of the valve opening. The Diagnostic Trouble Code (DTC) will be set when the PCM detects a short to ground in the Solenoid Signal or Return circuit.
What are the Possible Causes of the DTC P1037?
- Faulty Variable Valve Actuator (VVA) Solenoid
- Variable Valve Actuator Solenoid harness is open or shorted
- Variable Valve Actuator Solenoid circuit poor electrical connection
- Faulty Powertrain Control Module (PCM)
How to Fix the DTC P1037?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
