SOURCE: 95 gmc jimmy engine codes

9141 does not exist I will assume it is DTC P0141 HO2S Heater Performance Bank 1 Sensor 2

The VCM has the capability to monitor this process by using the Heated Oxygen Sensor (HO2S Bank 1, Sensor 2). The HO2S (Bank 1, Sensor 2), located in the exhaust stream before the catalytic converter, produces an output signal which indicates the storage capacity of the catalyst; this in turn indicates the catalysts ability to convert the exhaust emissions effectively. If the catalyst is functioning properly, the HO2S signal will be far less active than the signal produced by the Heated Oxygen Sensor (Bank 1, Sensor 1).
When the HO2S temperature measures below 360°C (600°F), the sensor will not produce any voltage and will behave like an open circuit. This will result in an Open Loop operation.
The HO2S heater provides for a faster sensor warm-up which allows the sensor to become active in a shorter period of time and remain active during long extended idle. The DTC P0141 determines if the HO2S is functioning properly by checking the response time of the sensor. This DTC is a type B DTC.

SOURCE: How do I remove the rear axle to replace the seal 1996 jimmy

You will have to remove the differential cover on the rear end, in the center of the gear cluster you'll have to rotate your axle until it exposes the ends of the axle shafts, push in the axles as far as you can from the brake pad assembly area, then, there this a C clips that slips into a groove on the end of the axle, you'll have to reove the C clip to pull out the axle.

SOURCE: 1996 jimmy gmc fuse box

Look on the driver's side fender well under the hood. Should be a long black rectangular box there. That is the power center or fuse block. The relays and fuses are inside. The top is not hard to remove. Hope this helped and best wishes.

SOURCE: How do I reset

If you’re not interested in diagnosing your car, truck, or SUV Check Engine Light, or it’s already fixed, and you just want the engine light out, visit an auto repair store.

Most stores will have a universal Check Engine Light Code Reader that can quickly and safely reset check engine light trouble codes. It should take about 30 seconds and is usually free..

SOURCE: 1996 GMC Jimmy will not shift into overdrive.

4th gear failure is a common problem with this transmission, assuming it is an automatic. You should have the vehicle checked for codes by a qualified repair center with the proper scan tool. Also, check fluid level and condition. More often than not, the trans loses 3rd and 4th gear, as these are working off the same set of clutches. 3-4 clutches apply in 3rd, and when the 4th shift is made the 2-4 band applies giving you overdrive. If you have no engine braking in manual 3rd, you definitely have a mechanical failure, no 4th could be an electrical, or mechanical fault.

2005 gmc savana reset check light after oil change


The Check Engine light has nothing to do with the oil needing to be changed. Please read on.

When the service engine soon light a yellow light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

    OPERATION

    When the term Electronic Control Module (ECM) is used in this guide it will refer to the engine control computer regardless that it may be a Vehicle Control Module (VCM), Powertrain Control Module (PCM) or Engine Control Module (ECM).
    The Electronic Control Module (ECM) is required to maintain the exhaust emissions at acceptable levels. The module is a small, solid state computer which receives signals from many sources and sensors; it uses these data to make judgments about operating conditions and then control output signals to the fuel and emission systems to match the current requirements.
    Engines coupled to electronically controlled transmissions employ a Powertrain Control Module (PCM) or Vehicle Control Module (VCM) to oversee both engine and transmission operation. The integrated functions of engine and transmission control allow accurate gear selection and improved fuel economy.
    In the event of an ECM failure, the system will default to a pre-programmed set of values. These are compromise values which allow the engine to operate, although at a reduced efficiency. This is variously known as the default, limp-in or back-up mode. Driveability is almost always affected when the ECM enters this mode.


    REMOVAL & INSTALLATION

    See Figures 1 and 2


    0900c152800a7f96.jpg enlarge_icon.gifenlarge_tooltip.gif

    Fig. Fig. 1: ECM mounting scheme-except 1996 models


    0900c152800a7f97.jpg enlarge_icon.gifenlarge_tooltip.gif

    Fig. Fig. 2: ECM mounting scheme-1996 models
    The ECM is located in the passenger side footwell in the kick panel up to 1996. In 1996, the ECM is located in the engine compartment next to the battery.

    1. Disconnect the negative battery cable.
    2. Disengage the connectors from the ECM.
    3. Remove the spring retainer off and over the rail of the ECM on vehicles except 1996.
    4. Slide the ECM out of the bracket at an angle.
    5. Remove the ECM.

    To install:
    1. Install the ECM into the bracket.
    2. Install the spring retainer (except 1996) and plug in the electrical connectors.
    3. Connect the negative battery cable.
