Various transmission shudder type issues may be corrected by updating the software in the powertrain and transmission control modules.
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.
Automatic transmissions can exhibit a variety of shifting and noise concerns due to failure of internal components. Our technicians tell us that due to the fact numerous updated parts are available for this transmission a complete inspection of all internal parts should be performed if the transmission is disassembled for overhaul.
Various driveability issues may be the result of low fuel pressure due to a failed check valve inside the fuel pump. If this is found to be the case the fuel pump should be replaced.
A dirty throttle body may cause low engine idle speed or frequent stalling, as oily residue blocks air flow in the throttle when the throttle is closed. Throttle body cleaning may be necessary to correct this condition. Our technicians caution against spraying cleaner directly onto the throttle body as this may damage the throttle position sensor (TPS).
An engine misfire may be caused by corrosion at the ignition coil and/or spark plug terminals or from cracked or brittle insulation on the spark plug wires themselves. Our technicians recommend complete inspection of the spark plug wires and replacement as necessary when engine misfires occur. If corrosion is noted on the coil towers or spark plugs those affected parts should be replaced as well.
Instrument cluster gauges, panel lamps, and electric door locks may not operate, and the courtesy lamps may remain on. These faults are commonly caused by "logic lock-up" of the body control module (BCM). If this is the case the BCM should be replaced with a revised version.
The anti-lock brake (ABS) warning light may illuminate with a scan tool showing "pump motor circuit" failure. The repair commonly involves replacing the pump motor relay and inspecting the build "date code" on the anti-lock brake controller. Some controllers require replacement based on the date code.
The fuel gauge may read empty when the fuel tank is full. Our technicians tell us there is a revised fuel level unit available which should correct this concern.
A hard starting and/or misfire condition may be caused by fuel pressure bleeding down from the fuel rail. If this is the case the fuel rail may be at fault and require replacement.
A moan or howl may be noted from the rear when the brakes are applied. It is recommended to check an repair or replace all rear brake components as necessary. If the noise is still present after repairs are completed then our technicians tell us that revised rear disc brake adapters are available which may help eliminate the noise.
