uses the same tps as the 5.7 vortec. GM said some of these vehicles have a condition in which drops of engine oil may be deposited on the exhaust manifold through hard braking. In most of the cases, all of these symptoms will show together making it easier to detect the faulty component. Production of the renowned 3800 V6 engine was officially ended in August 2008, nearly 10 years beyond the automaker’s original plan to cease 3800 engine production in 1999. If you replace the throttle body, the PCM won’t know and will continue to use the adaptive settings as if the carbon buildup is still in place. Condition: Some customers may comment on excessive engine coolant consumption, or an engine coolant leak near or under the throttle body area of the upper intake manifold. The 3800 was completely updated in ’95 when it became the Series II motor that was lower, lighter, smoother and more powerful than any of its earlier variations. 20% off orders over $120* + Free Ground Shipping** Online Ship-To-Home Items Only. a look at the “throttle position sensor” voltage. Locate the crankshaft balancer bolt.

Sensors and out puts calibration Let's start with the basic check list: 1. 1.1. That saves a lot of time because you don’t have to refer back to the component locator or circuit locations. At rest, this sensor outputs a relatively low voltage signal; as the arm/shaft is turned (as it would when the throttle opens), the output voltage increases. According to GM, there has been a running design change in the crankshaft balancer. 4. On the supercharged, it is located under a square metal plate, in similar location as EGR valve on the non-supercharged. Image by Flickr.com, courtesy of JOHN LLOYD. Eautorepair.net redraws factory wiring diagrams in color and includes the component, splice and ground locations right in their diagrams. Hold the flywheel using  J 37096 (see Figure 3).

Then repeat step #3 one last time. The deck height is shorter than the Series I, which reduced its weight and total engine package size. The IAC valve controls the amount of air the bypasses the throttle plate, and is used to control the idle speed of the engine. While that was fine for the 1960s, it wasn’t good enough in the ’70s and in 1977, Buick split the crank pins to make it into an even-fire motor with smother performance. The GM 3800 Series II engine, introduced in 1995, is quite a different engine from its predecessor, the Series I engine. One of the more frequent problems with modern vehicles is a bad throttle position sensor (TPS). Refer to the following procedure using (J 38197-MOD) for the revised design crankshaft balancer.
