    reference is 5 volts not 8

  • norman_rubi Oct 06, 2010

    There was no problem with battery. If 5 volt ref in computer is boosted to 8 volts manually, van will run ok. Once you shut engine off and try to restart, see same trouble...won't start. Have replaced orig computer, on which, boosting voltage to 8 volts, had no effect. Believe that 2nd computer is ok, somewhat. Why will van start ok if 5 volt ref in computer is boosted to 8 volts? And why will van not continue to read 8 volts needed?

    giving the other expert the poor rating was unfair, and 5 volts is the reference voltage of ALL OBD2 electronic engine control systems, seek professional help u are over your head here.

  • norman_rubi Oct 06, 2010

    The rating was not an insult by no means. I'm sorry that I offended you. I thought the rating was a standard to use IF answer was a help, not a judgement of your expertise or otherwise. Please accept my apology. Thank you.

Try unhooking your battery, take it Auto Zone for a full charge, then hook it back up in your vehicle, that should give the computer enough time to reset tiself to the full charged battery, They charge batteries for free by the way. 30 min's to an hr in most cases.

How to check the 5v reference circuit for short to ground Cadillac

Jun 10, 2017 | Cars & Trucks

1 Answer

Code P0115 Check Engine light on, fan runs continuously at high speed


The ECT sensor needs a power and ground to operate. It uses resistance to create a signal that is sent back to the computer. You can use a volt meter and check the plug for a 5 volt reference on one wire and the other wire will be a ground. If no 5 volt reference, look for a burned out fuse or broken/damaged wiring. A scan tool that shows data would be very helpful in knowing what the sensor is reading. The sensor may be reading properly and the problem may be due to a low coolant level or defective thermostat

03 chevy impala how to fix pocode 1635 is this the computer are what is it


DTC P1635
The powertrain control module (PCM) provides 5 volts to the following sensors:
?€¢
The manifold absolute pressure (MAP) sensor


?€¢
The exhaust gas recirculation (EGR) valve


?€¢
The fuel tank pressure (FTP) sensor


?€¢
The throttle position (TP) sensor

These 5-volt reference circuits are independent of each other outside the PCM, but are bussed together inside the PCM. Therefore a circuit condition on one sensor 5-volt reference circuit may affect the other sensor 5-volt reference circuits. The PCM monitors the voltage on the 5-volt reference circuit. If the PCM detects that the voltage is out of tolerance, DTC P1635 sets.
Diagnostic Aids
?€¢
If any sensor using a 5-volt bias voltage, such as the intake air temperature (IAT) sensor or fuel sensor, is shorted to voltage, DTC P1639 may set in addition to DTC P1635.


?€¢
For an intermittent condition, refer to Intermittent Conditions .

98 Durango 4x4 5.2 Get code crank-cam lose


Could be in the wiring, then, for those 2 sensors. I think they would both share the same 5 volt reference signal from the computer. When it stalls or goes into popcorn phase, a digital voltmeter (multi-meter) might help catch the missing signal, or it could be a poor connection for the ground for those two sensors, also. The ground connection would be known as an engine wire harness ground. But you can check the ground wire integrity at the sensor connector also.

To check the reference signal, ground voltmeter black lead to negative batt. terminal, and voltmeter red lead to sensor connector on the reference wire terminal (there's only 3 wires: reference (5 volt) wire, ground wire, and sensor signal wire to computer). Then turn key to ON. You should see very close to 5 volts at one of those terminals. If it had stalled and you had no signal, you would have to trace that wire back to the computer. By and by, you will probably need a wiring diagram.

Eng starts hard,runs good until the rpm is over 2200 then it stumbles my input voltage on the cam sensor is 5volts ,on most cars i've read should have 8volts where


Both crank and cam sensors have a 8 volt reference I have found the wiring melted together where it cross over transmission shorting out the signal. also test your reference voltage at the computer with circuit unplugged at sensor watch meter and wiggle wiring going back to computer this will help find faulty area.

How do I properly install a throttle position sensor on a 1981 Nissan 200sx?


The easiest way to find out about the voltage is to check the other sensors which would be on the same circuit. The engine temp sensor, Oxygen sensor, or MASS air flow sensor would be possible choices. This was one of the first years for fuel injection so the computer is a very simple setup compared to today.
On models built after 1990 the reference voltage is 5 volts. But on early models it could have been more.
Either way, the sensors get their power from the computer.
Normally you would install the TPS and set it at .5 volts with the throttle closed.

1997 dodge dakota how many volts does the crankshaft position sensor require


Code 320 is a problem with the tach signal which could be the crank or cam sensor.
Code 351 is a problem with the positive or negative circuit to the coil.
And code 1391 is for a problem with the ABS system which would not involve the engine running.
The sensors get a 5 volt reference from the computer and the return signal is what the computer "watches".
I would make sure you have battery voltage on the positive side of the coil and see if you have a ground reference from the computer.
You may need a shop manual to get the procedure to troubleshoot the ignition system.

Replacing e39 bmw abs brake pressure sensor


There is a brake pressure switch mounted on the ABS unit. It is a three wire sensor that needs a 5 volt reference, signal and ground. What can happen is the 5 volt reference from the module drops out and therefore the signal voltage drops out along with it. Few have replaced the brake switch itself and had the same problem. The module stops supplying the 5 volt reference to the brake pressure switch and the brake pressure switch cannot function properly. The replacement module will need to be coded after being installed.

4 cyl. 2006 G6. P0106 code is present, engine light is on, car hard shifts from 1st to 2nd gear (automatic). Mechanic states NOT the transmission, but, Map or Baro pressure circuit is out of range. Sensor...


you will need to some testing to islate problem

Turn ON the ignition, with the engine OFF.
Disconnect the MAP sensor.
Connect a voltmeter between the MAP sensor 5-volt reference circuit and a good ground.
Measure for a proper range of 4.8-5.2 volts between the MAP sensor 5-volt reference circuit and a good ground.
If the voltage is less than the specified range, then test the circuit for a high resistance. If the is normal, replace the ECM. If the voltage is more than the specified range, then test the circuit for a short to voltage. If the circuit is normal, replace the ECM.With the MAP sensor still disconnected, use the scan tool to observe the MAP Sensor parameter for the proper value of less than 12 kPa.
If the MAP Sensor parameter is more than 12 kPa, then test the MAP sensor signal circuit for a short to voltage. If the circuit is normal, replace the ECM.Connect a jumper wire between the MAP sensor 5-volt reference circuit and the MAP sensor signal circuit.
Use the scan tool to observe the MAP Sensor parameter for the proper value of more than 103 kPa.
If the MAP Sensor parameter is less than 103 kPa, then test the MAP sensor signal circuit for a high resistance. If the circuit is normal, replace the ECM.Turn OFF the ignition, and all electrical accessories. Allow sufficient time for the control module to power down before taking a resistance measurement.
Measure for a proper value of less than 5 ohms of resistance between the low reference circuit of the MAP sensor and a good ground.
If the resistance is more than 5 ohms, then test the circuit for a high resistance. If the circuit tests normal, replace the ECM.If the MAP sensor circuits test normal, then replace the MAP sensor.

P0208 injector problem


make sure injector gets 12 volts from ASD relay. then hook a volt meter from positive side of battery to injector driver circuit, it should fluctuate while trying to start. check fuel injector, should ohm at 12-13 ohms if lower it could be shorted......if the pcm injector driver is bad, the only fix is a new computer. you really need s scanner to properly diagnose this.
