The cam sensor outputs voltage pulses when the engine is running. The sensor is powered by the engine's computer, which typically provides 5VDC to power the sensor. With the engine not running, turn on the ignition switch. A cam sensor has three connections: Power (5VDC), signal output (% or 0 VDC varies with cam position), and ground return. Measure the signal voltage from the cam sensor wiuth repsect to ground. If it is 5V, slightly turn the engine's crank with a wrench until the cam sensor signal drops to zero volts. You should be able to see the signal voiltage switch between 5V and 0V while turning the crank slowly. If so, the sensor is working properly. If the signal doesn't change, the sensor is likely defective and should be replaced. They do fail.

SOURCE: Map sensor

Use a needle such as a sewing needle, stick it into each wire, and use your voltmeter from there.

No need for color codes....

SOURCE: Our Pontiac Bonneville ssei battery is charging at 14.9 volts

that is too high 14.4 should be the max.  However, a bad or weak battery may keep the voltage up.

SOURCE: P1296 No 5 Volts To MAP Sensor

The PAF sensor talks to the ECU and the ECUtells theNAF sensor when to talk. Any voltage to any sensor comes from the ECU. if you have jump started or shorted the sysrem, it coukd take out the ECU. we won't stop on that though, Now you need to go fuse chkg and make sure the Mass Air Flow is securely pligged into its connector. The MAF sensor is the first sensor in the ducting leaving the air filter. Do that before you ck fuses so you don't waste too much time. Good luck

The code was p0160 what does it mean.


This code is for a post-catalyst oxygen sensor that isn't operating properly or not at all. The catalyst, or catalytic converter is used to control emissions. This particular o2 sensor on Bank 2, position 2 is after the converter on bank 2 and monitors the catalyst efficiency of the catalytic converter on that bank. The P.C.M (Power train Control Module) compares the post-cat o2 sensor to the pre-cat o2 sensors to measure the cat's efficiency. The o2 sensor is a four wire sensor. The P.C.M supplies a reference voltage to the sensor of about half a volt and also supplies a sensor ground. 12 volts are supplied for the heater element and also a ground for the heater element (the heater in the sensor helps the sensor to warm up faster which allows the engine to reach closed loop sooner). The sensor varies the reference voltage the P.C.M gives it based on oxygen content of the exhaust. The change in oxygen content causes resistance changes in the sensor which affects the 0.5 volt reference voltage. Oxygen sensors are capable of varying the supplied voltage between 0.1 volts to 0.9 volts. Lean exhaust produces low voltage and causes the supplied 0.5 volts to drop. Rich exhaust produces high voltage and causes the supplied 0.5 voltage to increase. Pre-catalyst (front) o2 sensors switch between low and high voltage rapidly one or two times per second. However this sensor is a post-cat o2 sensor and may switch much slower & not vary as much (this is normal). If the sensor "sticks" or there are too few switches in a given time period, P0160 may set.

1999 jeep tps voltage to high


Well, it could be the computer, the sensor, or a problem in the wiring harness.
The computer sends a 5 volt reference to the sensor and it should return something like .5 volts when the throttle is closed. As the throttle is opened the resistance goes down and the return voltage goes up.
If the return voltage is the same as the input, the sensor is shorted internally. Or something is going on in the wiring harness.
The 5 volt reference is aprox, it should be the same as the other sensors. So 5.7 volts may be ok coming from the computer.

Explain these trouble codes po123,p0118 and 1193


Is it high voltage or signal high. If it is truly high voltage it could be a wire crossed with a 12 volt wire, but more likely an engine controller that has gone bad. Use a digital volt ohm meter to determine the voltage on the reference circuit. Normal voltage should be near 5 volts.
If the issue is signal high, this indicates a broken wire between the engine controller and the sensors.
Good luck.

What would cause high voltage for the tps?


There are three wires to the TPS. One is ground, one is 5 volts, and the middle one is variable between 5 and 0 volts,depending on throttle position. If you lose the ground somewhere, the 5 volts will go straight to the middle one, no matter where the throttle is. Check these with a good volt meter. If the ground is good and the 5 volts is good ans the middle one is still always high, it's a bad sensor.

I have a 2003 impala and its reading 5 volt reference voltage circuit condition. what do i need to fix this problem? The problem is causing my car to idle up to high. First the codes read that i needed...


all your sensors run off the 5 volt ref. so you will have to trace your wiring harness from the pcm\ecm all the way out under the hood to locate the broken or pinched wire.

Oxygen sensor


O2 voltage should vary between about .10 volts and 1.0 volts with the engine in closed loop mode. low volts mean lean, high, rich, if the voltage is always low (<.20V) even when you goose the throttle chances are the O2 is done. Remember high/low voltage readings indicate lean rich conditions, a failed O2 has almost no drive symptom, just a check engine light.
