How to replace head gasket on a 05 scion tc 1.5L


If you are asking the question let a mechanic do it. The gasket is cheap but it involves a lot of work and some experiance. Look in a Chilton book for that model and you'll get an idea of whats necessary.

Truck is a 1999 isuzu npr,motor : 4HE1-TC,Trans: auto_ AISIN SEIKI Ser. #9C0756,Mileage 130 K Transmission will not engage in drive or second,if you put in 1 st position truck will jump as it is supposed...


Check sensors on the transmission. Best way to do it is a network diagnostics test. This will tell you exactly which sensor it is. It may just be a sensor with corrosion, try cleaning each sensor.

Scion tc wont start


Be careful with ether. Some newer engines are 0 clearance and can smash valves if they backfire.
check compression and timing.

Hi my Saab 2001 93 2.0 turbo convertible has lost power get into limp home mode I reset it every few weeks codes come up p1105 p1260 p1251 p 1264 what do u think is wrong ?


code p1105 refers to manifold absolute pressure(MAP) sensor, TC system-leak detected. causes ---intake leak, ---hoses There are to references to p1105 The second response is still map sensor but the causes are---TC system--mechanical fault--air leak between throttle body-TC,map sensor---TC system--exhaust blockage
code p1260 refers to throttle return spring--weak spring force. causes ---mechanical fault,--,throttle control unit
code p1264 refers to throttle valve opening-accelerator released causes ---throttle control unit---mechanical fault

How to adjust valves on a 2006 scion tc


your toyota tech dont know his/her cars the engines lifters are solid not hydr then to adjust them they have to remove the cams and measure the lifter bucket thickness then re install the proper size and re install and no this is not done
every 15k it would cost a grip it is done during cyl head rebiulding another unlikely scenario (with proper care)

2005 scion tc having transmission problems


U have internal transmission hydraulic leaks, the new fluid temporarly softened and sealed the leaks, but that is only temp fix, u will need to overhaul the trans to correct this.

Ther first code ECM-6805 TURBOCHARGER (TC) CONTROL VALVE DIAGNOSTIC TROUBLE CODE (DTC) INFORMATION If engine speed (RPM) is above 3500 rpm and the engine is operating at a high load, and if the boost pressure (from the boost pressure sensor) is higher than a designated value, which at maximum boost pressure is approximately 20kPa (2.9psi) above normal boost pressure, this is interpreted as a fault and diagnostic trouble code (DTC) ECM-6805 is stored. Condition reduced boost pressure Possible source * hoses between turbocharger (TC) and turbocharger (TC) control valve respectively turbocharger (TC) control valve and pressure servo are loose or are blocked/damaged * faulty turbocharger (TC) control valve * faulty boost pressure control (BPC) valve pressure servo * sticking boost pressure control (BPC) valve Condition * none ECM-6805 TURBOCHARGER (TC) CONTROL VALVE PRESSURE TOO HIGH - PERMANENT/INTERMITTENT FAULT Checking the hoses and turbocharger (TC) control valve Check that the hoses between the intake manifold, pressure regulator and turbocharger (TC) control valve are not trapped, blocked or damaged. Check the turbocharger (TC) control valve by activating it. Check the alignment of the boost pressure control (BPC) valve pressure servo and the boost pressure control (BPC) valve and that they are functioning correctly and not sticking according to See: Component Tests and General Diagnostics\Boost Pressure Regulator, Checking/Adjusting Verification Hint: After carrying out the repair, check that the fault has been remedied. * Ignition off. * Reinstall connectors, components etc. * Disconnect the VCT 2000 from the data link connector (DLC). * Test drive the car and check that high boost pressure is obtained. * Connect the VCT 2000 to the data link connector (DLC). NOTE: Do not switch off the ignition before the VCT 2000 has been connected and the boost pressure has been tested with the smart tool. Read the boost pressure fault status When the boost pressure has been tested the display should show that the diagnostic is complete. the second code Symptoms You will likely not notice any serious drivability problems, although there may be symptoms. Possible Solutions The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures: Inspect for the following conditions: An incorrectly routed harness--Inspect the harness of the MAF sensor in order to verify that it is not routed too close to the following components: - The secondary ignition wires or coils - Any solenoids - Any relays - Any motors A low minimum air rate through the sensor bore may cause this DTC to set at idle or during deceleration. Inspect for any vacuum leaks downstream of the MAF sensor. A wide open throttle (WOT) acceleration from a stop should cause the MAF sensor g/s display on the scan tool to increase rapidly. This increase should be from 6-12 g/s at idle to 230 g/s or more at the time of the 1-2 shift. If the increase is not observed, inspect for a restriction in the induction system or the exhaust system. The barometric pressure (BARO) that is used in order to calculate the predicted MAF value is initially based on the MAP sensor at key ON. When the engine is running the MAP sensor value is continually updated near WOT. A skewed MAP sensor will cause the calculated MAF value to be inaccurate. The value shown for the MAP sensor display varies with the altitude. With the ignition ON and the engine OFF, 103 kPa is the approximate value near sea level. This value will decrease by approximately 3 kPa for every 305 meters (1,000 feet) of altitude. A high resistance on the ground circuit of the MAP sensor can cause this DTC to set. Any loss of vacuum to the MAP sensor can cause this DTC to set. the third code O2 sensor failure may not be displayed appropriatly
