Code P1037 Jeep 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.

- 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)

Frequently Asked Questions about P1037 Jeep Code
1. What does OBDII code P1037 mean on a Jeep?
Code P1037 indicates a "Cylinder 1 Oil Supply Solenoid Valve Driver Short To Ground," meaning there’s an electrical issue in the oil supply solenoid valve circuit for cylinder 1.
2. What are the common symptoms of P1037 on a Jeep?
Symptoms may include rough idling, engine misfires, reduced fuel efficiency, poor acceleration, or the Check Engine Light being illuminated.
3. What causes the P1037 code to appear on a Jeep?
The most common causes are a short to ground in the oil supply solenoid wiring, a faulty oil supply solenoid, or a damaged Engine Control Module (ECM).
4. Can I drive my Jeep with the P1037 code?
It’s not recommended to drive with this code as it may cause further damage to the engine, especially if it leads to improper oil flow or cylinder performance.
5. How do I diagnose the P1037 Jeep code?
Start by inspecting the wiring and connectors for the cylinder 1 oil supply solenoid for damage or shorts. Use a multimeter to check for continuity and test the solenoid itself for proper function.
6. What tools are needed to fix the P1037 code on a Jeep?
You’ll typically need a multimeter, an OBDII scanner, and basic hand tools to inspect and replace components like the solenoid or wiring.
7. How much does it cost to repair the P1037 code on a Jeep?
Repair costs can vary, but replacing the oil supply solenoid typically costs between $100 and $300, including parts and labor.
8. Could a low oil level trigger the P1037 code?
While low oil level might not directly cause P1037, it can contribute to poor oil flow, which could exacerbate solenoid or cylinder issues.
9. Does the P1037 code require replacing the oil supply solenoid?
Not always. The issue might be with the wiring or connectors. Replace the solenoid only if it’s tested and confirmed to be faulty.
10. Will clearing the P1037 code fix the issue?
Clearing the code may turn off the Check Engine Light temporarily, but the underlying issue must be addressed to prevent the code from returning.
