How involved is replacing a valve on 2003 malibu???? And more importantly how much does it cost?????
This is actually a big job,the radiator has to be drained, the intake and exhaust manifolds have to be taken off, the heads have to be removed and the valves replaced. The heads have to be checked for warp. The mating surfaces have to be cleaned and new gaskets appplied, the unit has to be reassembled , A lot of shops will just get a pre-assembled head with a warranty. You are looking at a bill of 200 to 400 for heads, then gaskets and coolant, the labor is about 100 an hour, so you are near 2000 USD when all is said and done.
2007 chev malibu po62f internal control module EEPROM error ? what dose it mean
Whenever the ignition is on and the PCM is energized, EEPROM self-tests are initiated. In addition to running internal controller self-tests, the controller area network (CAN) also compares signals from each individual module to ensure that each controller is functioning properly. These tests are performed simultaneously. If the PCM detects discrepancies in EEPROM functionality, a code P062F will be stored and a malfunction indicator lamp (MIL) may be illuminated. Additionally, if the PCM detects a problem between any of the on-board controllers, which would indicate an internal EEPROM error, a code P062F will be stored and a malfunction indicator lamp (MIL) may be illuminated. Multiple failure cycles may be necessary for MIL illumination, depending upon the perceived severity of the malfunction.
Causes for this P062F DTC code may include:
Defective controller or programming error, Overheated PCM, Water damage, A bad controller power relay or blown fuse, Open or shorted circuit or connectors in the CAN harness Insufficient control module ground Faulty EEPROM.
2007 malibu, driving 65 mph, power steering warning on dic, error on odometer, speedometer quit working, transmission downshifts rpm to 5000 (i guesslimp mode),shut off in drive way, now won't start.
what do I try next? You take your vehicle to a qualified repair shop. You have no idea of the complexity of the electronic's on your vehicle . Disconnecting battery cables an touching them is not the answer . Having a qualified professional with proper diagnostic tools checking computer system's is . One bad module on the GMLAN serial data network is all it takes for a no start . You have no idea what happens when you turn the key to start your vehicle.
Circuit Description
For ignition switch power modes refer to Body Control System Description and Operation. Once the ignition is placed in the Run/Crank position, the control circuit of the Run/Crank relay is grounded by the body control module (BCM). With the Run/Crank relay switch closed, battery positive voltage flows through it and on to the park/neutral position (PNP) switch. With the PNP switch in either the Park or Neutral position, battery positive voltage will flow to the starter relay coil supply voltage input terminal of the engine control module (ECM) and the coil side of the starter relay. Placing the ignition in the START position sends a message to the engine control module ECM requesting engine start. If the ECM has determined that the transmission is in Park or Neutral and theft is not active, it will ground the control circuit of the starter relay. Battery positive voltage will then flow through the switch side of the starter relay to the S terminal of the starter solenoid, cranking the engine.
Also with power steering warning on ,DTC'S are stored in the control module for the electric power steering an or the BCM - body control module . I have seen bad power steering control modules short out the data bus (network) .
Do yourself a favor an take it to a qualified repair shop.
My 2007 chevy malibu will not start when I turn the key everything else works radio lights what is wrong?
Hooking up a factory or professional scan tool to see where the crank signal is getting lost at would be the easiest way . You obviously don't know how this works .
