The AC/heater (HVAC) system may unexpectedly switch to the defrost mode when accelerating. This system is operated by engine vacuum and should be inspected for any vacuum leaks if this problem develops. There is also a revised vacuum check valve available to address this concern.
Some automatic transmissions may set a code P1740, torque converter fault. Our technicians tell us there is a revised transmission pressure boost valve cover plate to correct this condition.
An intermittent connection in the crank position sensor wire connector can cause poor engine performance or the engine may crank but not start.
Insufficient fuel pressure may be caused by particulate contaminates or other type of substances by-passing the primary fuel pick-up screen and resulting in fuel pump failure. Our technicians recommended to replace entire fuel pump module assembly as two (2) filters, primary and secondary are included with the assembly.
The engine may exhibit excessively high oil pressure at cold start up. This may lead to distortion of the oil filter case. Inspect the oil filter case for any signs of distortion. If the case is distorted, Connect an oil pressure gauge to the engine and start the engine while observing the readings. If the pressure reads above 80 psi, replace the oil pump.
The blower motor may operate erratically and the blower switch operation has a sticky or mushy feeling, the detents almost non existent. Our technicians tell us that the blower switch should be removed and inspected for overheating. This is common if the blower motor is frequently operated on high speed as the current flow through the switch tends to melt internal the components. Also carefully inspect all of the switch connector terminals for discoloration due to overheating and replace as required. A poor electrical contact at the connector will also cause the switch to overheat.
Leak detection pump failure can be caused by the internal diaphragm switch sticking, or in some cases, contamination from debris or carbon particles from vapor canister. If black carbon particles are present in the LDP, replace vapor canister in addition to LDP. The purge solenoid should also be checked for debris or carbon contamination and replaced as necessary. All evap system hoses are subject to cracking and splitting causing leaks, Inspect hoses carefully. In cases of contamination from carbon particles or debris, all hoses and tubes must be blown out with compressed air to remove contaminates.
