P1585 Scion Code - Acceleration Sensor Circuit
Quick Answer
The Engine Control Module (ECM) determines the vehicle inclination based on a signal from the Airbag Sensor Assembly (Yaw Rate and Acceleration Sensor). Common causes include Faulty Airbag Sensor Assembly (Yaw Rate and Acceleration Sensor), Airbag Sensor Assembly harness is open or shorted, Airbag Sensor Assembly 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.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
- Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
- Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
- Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
- Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
Frequently Asked Questions about P1585 Scion Code
1. What does the OBDII code P1585 mean in a Scion?
The P1585 code indicates an issue with the Acceleration Sensor Circuit in the vehicle, which monitors acceleration and deceleration for proper engine and transmission performance.
2. What are common symptoms of the P1585 code in a Scion?
Symptoms may include poor acceleration, reduced engine performance, the check engine light turning on, and possibly erratic shifting in some models.
3. What causes the P1585 code to appear in a Scion?
Common causes include a faulty acceleration sensor, damaged wiring or connectors in the sensor circuit, or issues with the engine control module (ECM).
4. Can I drive my Scion with the P1585 code?
It may be possible to drive the vehicle, but doing so can lead to poor performance and potentially cause further damage. It’s best to address the issue promptly.
5. How is the P1585 code diagnosed in a Scion?
A mechanic will use an OBDII scanner to confirm the code, inspect the acceleration sensor and its wiring, and test the sensor’s output voltage against manufacturer specifications.
6. How do I fix the P1585 code in my Scion?
Repairs may include replacing the faulty acceleration sensor, repairing or replacing damaged wiring or connectors, or reprogramming or replacing the ECM if necessary.
7. How much does it cost to fix the P1585 code in a Scion?
Repair costs vary depending on the issue, but replacing an acceleration sensor typically costs between $100 and $300, including parts and labor.
8. Can a dirty acceleration sensor cause the P1585 code?
While rare, a dirty sensor could potentially interfere with its readings. Cleaning it might help, but if the sensor is damaged, it will need to be replaced.
9. Does the P1585 code require ECM replacement in a Scion?
ECM replacement is usually a last resort and is only necessary if the ECM itself is diagnosed as faulty after ruling out sensor and wiring issues.
10. How can I prevent the P1585 code from recurring in my Scion?
Regular maintenance, including inspecting and replacing damaged wiring or sensors as needed, can help prevent the code from recurring.
