Engine Does Not Start

What it means

This is a Toyota hybrid-specific code; the same number may mean another fault on other makes. In a hybrid, the system spins the gasoline engine with an electric motor-generator, and this code sets because the engine turned but did not start within the expected time. The most common cause is running out of fuel, followed by fuel pump or ignition problems.

Models covered: Toyota hybrids (e.g. Prius, Camry Hybrid), mainly earlier generations.

Symptoms4

• Hybrid system warning and check engine light.
• The car moves on electric power only for a short distance, then loses power or stops.
• The engine is heard turning over without starting.
• The hybrid battery charge may drop quickly.

Possible causes6

• Out of fuel, sometimes with less fuel than the gauge shows.
• Failed fuel pump, or its relay or fuse.
• Ignition fault such as an ignition coil or spark plugs.
• Failed crankshaft position sensor.
• Blocked air intake or a very dirty throttle body.
• Low engine compression (rare).

How to diagnose5

1. Confirm there is enough fuel in the tank; do not rely on the gauge alone.
2. Check the 12V auxiliary battery and terminals, since it powers the system computers and a weak one causes confusing faults.
3. Read other codes with a Toyota-capable hybrid scan tool; crank sensor or fuel codes set the direction.
4. Confirm the fuel pump runs and measure fuel pressure.
5. Check for spark and plug condition, and use Toyota's maintenance mode to run the engine when needed.

How to fix5

1. Refuel and clear the code if the tank ran dry.
2. Replace the failed fuse, relay or fuel pump.
3. Replace faulty plugs, coil or crank sensor.
4. Clean the throttle body and clear any intake blockage.
5. Clear the codes and confirm the engine starts on its own when needed while driving.

Repair cost

In Saudi riyals; the highlighted part is the expected range for this fault.

Refueling or a fuse or relay is at the low end; a fuel pump or crank sensor with labor raises the cost to the top of the range.

Prices are rough estimates for common cars at independent workshops and vary with the car and the source of the part.
