Trouble Shooting: Notes
WARNING: This page is about a different car, the 1988 Mitsubishi Galant Sigma. However, it is still accessible from the selected car via links, so may be relevant.
A malfunction in the electronically controlled power steering system will usually cause hard steering at idle or low-speed driving, or too sensitive steering during high-speed driving. However, these problems do not necessarily indicate a malfunction in the electronically controlled power steering system. Always check the following components and conditions first before trouble shooting for an electrical problem in the system.
- Loose or damaged V-belt.
- Tire condition and pressure.
- Ball joints and suspension condition.
- Steering linkage condition and lubrication.
- Front wheel alignment.
- Steering gear box mounting.
- Bent steering column and/or rack.
- Power steering system fluid leakage.
- Power steering pump pressure.
If all of the above conditions and components have been checked and are found to be okay, the problem may be in the electrical system. Before testing any major electrical component in the system, visually check for loose or damaged electrical connectors, bad fuse, damaged wiring or a damaged speed sensor.
