SOURCE: 1999 pontiac grand prix . will not run

If wiggling the wires cured the code, then one of the wires is broken inside the insulation. Pull on each wire one at a time. look for the colored insulation to stretch, this will be the broken wire. For the other car that wont rev up, this is a common when the catalytic concverter is plugged up. This will also cause MAF codes, and in turn, TRAC OFF light.

SOURCE: Wheel Speed Sensor on a 99 Grand Prix

i use a scanner to check to see all wheel sensors.getting a signal . it take two people. your scanner have to be type to check abs system. you can use ohms meter . it will tell you your wheel sensor is open or shorted out.

SOURCE: 2002 grand prix runs rough,dies service engine

sounds like you have a vacuum leak, check all the vacuum hoses and replace any broken or kinked ones, also check around the intake manifold gasket for leaks. any air leaks after the air flow meter creates 'un-metered' air which inturn will make the car run rough and stall, hope this helps

SOURCE: the trac off light comes on and car jerks.

check the inlet hose for the air from the air cleaner assembly to the throttle body.there is a sensor mounted on the hose.make sure the sensor is not loose at the base or a poor seal.it can be sealed up with silicone .there may also be a crack in the hose flex part.a vacuum leak in this hose will cause the traction control light to come on and erratic running.when torque is applied,the engine moves, and a leak appears.
this problem fools alot of mechanics into checking the abs and traction systems.

Can the input speed sensor on a 2009 GMC Acadia be changed without having to remove the transmission


Did you do the diagnostic's that go to that code ?

P0716
Circuit/System Description
The input speed sensor (ISS) is a hall-effect type sensor. The sensor faces the 1-2-3-4 and 3-5-R clutch housing machined teeth surface. The sensor receives 8.3-9.3 volts on the input/output speed sensor (ISS/OSS) supply voltage circuit from the transmission control module (TCM). As the 1-2-3-4 and 3-5-R clutch housing rotates, the sensor produces a signal frequency based on the machined surface of the 1-2-3-4 and 3-5-R clutch housing. This signal is transmitted through the ISS signal circuit to the control solenoid (w/body and TCM) valve assembly. The control solenoid (w/body and TCM) valve assembly uses the ISS signal to determine line pressure, transmission shift patterns, torque converter clutch (TCC) slip speed and gear ratio.

Circuit/System Verification
Engine idling, observe the scan tool Transmission ISS parameter while varying the engine speed. The Transmission ISS parameter should change with the engine speed and not drop out.
Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.

Ignition OFF, remove the control valve body cover. Refer to Control Valve Body Cover Replacement.
Connect the TCM harness connector.
Disconnect the input speed sensor (ISS) from the control solenoid (w/body and TCM) valve assembly.
Connect the J 38522 between the supply voltage terminal B and ISS signal terminal A at the control solenoid (w/body and TCM) valve assembly. Refer to Control Solenoid Valve and Transmission Control Module Assembly Input Shaft Speed/Output Shaft Speed Input Test for further instructions.
Set the J 38522 signal to 8 volts, the frequency to 120 and the percent duty cycle to 50.
Ignition ON, observe the scan tool Transmission ISS parameter. The scan tool Transmission ISS parameter should be between 100-400 RPM.
? If not within the specified range, replace the control solenoid (w/body and TCM) valve assembly.
If all circuits test normal, test or replace the input speed sensor.

Control Valve Body Cover Replacement

Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection.
Remove the air cleaner assembly. Refer to Air Cleaner Assembly Replacement.
Remove the oil cooler inlet hose (1) from the retainer on the control valve body cover.
Remove the oil cooler outlet hose retainer nut (5) from the control valve body cover.
Remove the oil cooler outlet hose (4) from the retainer on the control valve body cover.
Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle.
Remove the left engine splash shield. Refer to Engine Splash Shield Replacement.
Drain the transmission. Refer to Transmission Fluid Replacement.

you don't need to pull thr trans .

What does error code P0716 mean on a 2001 Volvo S80?


Trouble Code: P0716
Input Speed Sensor Performance
Possible Causes:


P0716 The TCM detects an unrealistic drop in input shaft speed. ISS DTC P0716 is not failed this ignition. Transmission input speed is 1,050 RPM or greater for 2 seconds. Transmission input speed drops 1,000 RPM for greater than 4 seconds and does not recover with in greater than 0.80 seconds.

Go to a Volvo mechanic for specific help, they will probably replace a faulty sensor.

Best of luck.

The blinking light is telling the driver the problem is serious. You need compression, fuel, and spark at the right time for the cylinders to produce power. I'll assume compression is ok, so that leaves the fuel injector or spark from the coil.

AUTOMATIC TRANSAXLE DIAGNOSTIC TROUBLE CODES P0715, P0716, P0717, P0720, P0721 & P0722

An improperly functioning input speed sensor or output speed sensor may result in the following conditions:
^ "Check Engine" light on
^ Harsh P-R or P-D engagement shock
^ Transaxle in 3rd gear fail-safe
^ Diagnostic trouble codes 1. Using a GDS, check for DTCs in both the "Engine" and "Automatic Transaxle" menus. Record the DTC and description.
2. From the GDS, select:
^ Vehicle
^ "Auto Transaxle" menu
^ "Current Data"
^ "Input speed sensor" and "output speed sensor". Drive the vehicle and monitor the input and output speed sensors. If the sensors show:
^ Continuous output, the wiring currently has no open/shorts. Go to Step 6.
^ No output, go to Step 3
3. Check the wiring harness visually for an open circuit or short circuit to ground. Check for a pinched harness at the PCM/TCM attachment bolts.
4. Disconnect the connectors at the input and output speed sensor and PCM/TCM. Check for bent pins or pins not fully inserted into the connector.
5. If a harness open/short is found, repair or replace the ECM control harness between the PCM/TCM and transaxle and go to Step 8. If not, go to Step 6.

99 Grand Prix idles funny, dies got code p0102,


this vehicle most likely has a mass air flow sensor it may have got accidently unplugged or the air tube from mass airflow to engine is not connected well or it could be that you have indeed a bad mass air flow sensor they do make a special cleaner that you may want to try before purchasing a mass air flow sensor or purchasing one from salvage yard the symptoms you describe would be created by a bad massair flowsensor
