Sunbeam Ti (1979-83)

COMMON FAULTS

Please Note: Common Faults in Regularly Used Vehicles vs. Low-Mileage Stored Vehicles that have been used consistently over many years, accumulating approximately 10,000–12,000 miles annually, are more prone to common faults due to regular wear and tear. These issues typically arise from the natural aging of components subjected to frequent use, such as engine parts, suspension systems, brakes, and tires. In contrast, vehicles with low mileage that have been stored or preserved are likely to experience different types of issues. These vehicles are often better maintained to ensure their longevity and may avoid some of the typical wear-and-tear problems seen in regularly driven cars. However, they can still face unique challenges such as degradation of rubber seals, corrosion from prolonged inactivity, or fuel system issues caused by old or stagnant fuel.

The **Sunbeam Ti**, a limited-production variant of the Chrysler Sunbeam, had a few common faults: 

1. **MPET IPD Faults**: These faults could occur when the motor is not connected to the IC, the MPET IPD current threshold is set too low, or the motor inductance is too low. Adjusting the current threshold or manually measuring resistance and inductance can help resolve this. 

2. **MPET BEMF-Constant Measurement Fault**: On high-resistance motors, the MPET Ke fault might trigger if the open-loop current reference is too low. Increasing the reference value or manually measuring motor parameters can address this issue. 3. **Abnormal BEMF Fault**: Lower BEMF constant motors may trigger this fault when Auto handoff is enabled with a minimum BEMF threshold of 0 mV. Disabling Auto handoff and setting a higher BEMF handoff threshold can solve it. 

4. **Motor Startup Failure (Align Startup Method)**: If the rotor doesn't align due to short align time or low align current, the motor may fail to start. Adjust align time and current to prevent rotor oscillations after alignment. 

5. **Motor Startup Failure (IPD Startup Method)**: High IPD clock frequency can cause startup failure, especially for high-inductance motors. Decreasing the IPD clock frequency can help. 

6. **Speed Overshoots During Handoff**: Sudden phase current changes during open-to-closed loop transition can lead to motor speed overshoot and acoustic noise. Remember that individual experiences may vary, and proper maintenance plays a crucial role in preventing these faults.
