Cars without ABS suffer master cylinder failure. The brake pedal will be spongy in feel, the pedal travel will seem excessive, and overall braking performance will be poor.
When a no start condition is caused by a faulty camshaft or crankshaft sensor, related fault codes stored in the powertrain control module (PCM) should not be trusted. Our technicians tell us that under certain conditions a fault code can be stored for the "good" sensor. Care should be taken to properly diagnose this condition.
If a Check Engine Light illuminates indicating leak detection pump (LDP) failure, the cause is often pinched or disconnected vacuum lines to the pump. Vacuum lines should be inspected before replacing the leak detection pump. Contamination (carbon or debris) in the pump can cause failure and any hoses should be cleared before a new pump is installed.
There have been reports of premature head gasket failure; an updated gasket design is available to correct this problem.
