Their is no calibration for this tps. Did You Know… Low Mount 3800 ALT! If degradation is not apparent, evaluate the vehicle for other causes of excessive coolant consumption as noted in the Engine Diagnosis section of the appropriate service manual. Over time, carbon buildup can accumulate around the throttle plate, changing it’s “home” position. GM has changed the calibration requirement of the forward-facing camera, which GM refers to as the "frontview camera module". You just said codes. 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. Low Mount 3800 ALT! If the buildup occurs gradually, the PCM “learns” the new home position. In those vehicles, the “gas” pedal isn’t connected to the throttle body by a cable. Low mounts in stock today. They include wiring diagrams and technical service bulletins. If degradation of upper intake manifold composite material is found, replace the lower and upper intake manifolds with the following part numbers: Part Number    Description The J 38197-4 bolts are silver, while the previous tool uses black bolts. With the scanner connected to the ALDL, and the throttle closed, see what the voltage reading is. The data is cut-and-paste compatible with HP-Tuners, but can also be reformatted for EFI-Live, SCT, and other popular tuning platforms. News OBDII ProgramminG News. The TPS sensor is reading incorrectly. Sensors and out puts calibration Let's start with the basic check list: 1. b. One that indicates throttle closed and one that indicates WOT (wide open throttle). This increased fuel mileage by a substantial margin and provided GM some engineering success. TPS calibration on 3800's . The GM 3800 Series II engine, introduced in 1995, is quite a different engine from its predecessor, the Series I engine. The blue signal wire is giving me 4.5 volts at idle as if the idle is WOT. General Motors Issues Recall on 3800 V6 Powered Vehicles Then turn the key back on clear the codes and the tps is reset to 0. this car has a previous history with the same issue. 2) After 3 minutes, turn the engine off and leave it off for 60- seconds. Source: GM media and Engine Builder magazine. J 38197-1 Pilot Screw DW GM Calibration Summaries are available for most of the popular DW GM part numbers. Then repeat step #3 one last time. Refer to the arrow in the illustration of the upper intake manifold (see Figure 1). The hole is used to identify the crankshaft key location in relation to the slot in the crankshaft balancer. in. Many car makers including GM started installing fly by wire electronic throttle bodies. In most of the cases, all of these symptoms will show together making it easier to detect the faulty component. d. Remove the J 38197-1, 2 and 4 from the crankshaft balancer. If you’ve replaced your GM electronic throttle body or you’ve disconnected the battery, you must do a GM throttle body relearn to establish a new baseline idle. Tighten the bolt to 150 Nm (111 lb.-ft.) + 76° using J 36660. Unfortunately, the engine still had a severe primary imbalance because it was a 90° block with a 120° firing order. Because of its longevity and use in various GM vehicles, it’s probably an engine that you have become accustomed to seeing in your shop for routine service. Here are the Symptoms of a Bad Throttle Position Sensor. The TPS reports the throttle position to the engine control module, which uses the signal to adjust fuel delivery and ignition timing. 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. Do you have a GM car between 1980 to 1995? This test will help you to confirm if these 5 Volts are present or not. a. Invert the J 38197-2 so that the leg of the tool is facing away from the crankshaft balancer. J 38197-A and J 38197-MOD Crankshaft Balancer Puller (If you already have J 38197, it is necessary to only order the J 38197-MOD). 3.8L V6 Buick (or Chevy, Olds, Pontiac) needs power to work.. Find the perfect fitting and complete solution for your 3800 with the Northstar Throttle Body Kit. To obtain the latest electronic controller calibration information for your vehicle, enter the vehicle's 17 character Vehicle Identification Number (VIN) and select 'Get CAL ID'. Be advised that the procedure used to service the crankshaft balancer has been revised. Disconnect the TPS sensor from the harness. The crankshaft balancer designs can be easily identified by a dimple stamped in the face of the crankshaft balancer (see Figure 2, view B). The result was a 205 hp and 230 lb.-ft. powerplant that had better fuel economy. A new intake manifold improved breathing, while a redesigned cylinder head featured larger valves and a higher compression ratio. I looked this up in si2000 and it shows the 2000 m.y. a look at the “throttle position sensor” voltage. Refer to the following procedure using (J 38197-MOD) for the revised design crankshaft balancer. Our base kit includes CNC machined adapter plate w/ screws, MAP adapter hardness, custom throttle cable, a silicone coupler, and 2 clamples for the coupler. Follow the lower and upper intake manifold installation instructions found in the Engine Unit Repair section of the appropriate service manual. While the stroke for the 3.8L engine remained at 3.4” (86 mm), and the bore remained at 3.8” (97 mm), the engine architecture changed dramatically. The TPS voltage reading is how the ECM knows in what position the throttle blades are. 3) Start the engine again and let it idle in park for 3 minutes one more time. The revised crankshaft balancer requires the use of three bolts (J 38197-4). The only thing that pushing the gas pedel does is on some models is to reset the oil life index.
