While i'm not sure if there are mechanical tachometers like speedometers electronic tachometers are quite simple. An electronic tachometer works like an old analog volt meter. The speed of the engine is converted to a voltage. The voltage is fed to the moving coil. The coil creates a magnetic field. That field of the coil tries to align itself with the ...

When I looked online, here's what I found about the location of the MAP sensor in your car. As always, a picture is worth a thousand words: From looking at other info about that car it's port injected, not throttle body injected (individual injectors on each cylinder, not just one on the throttle body). As far as I know there should never be fuel in that ...

Figured out it (thanks to a shove in the right direction by @mikes): It's the remote engine start accessory's antenna. I didn't think of it when I was asked if I had "add-ons" because it's an official Honda accessory (that I can't do without!) installed by the dealer before taking delivery. Specifically, see this exploded diagram part #4: I went back ...

Here's a rough approach that should work regardless of vehicle You will need to know the current brake pad thickness the thickness of a brand new brake pad how much mileage you've put on the car since the last brake pad change. The formula Mileage per mm = mileage since last brake change / ( brand new thickness - present thickness ) ...

You need Spark, Fuel, and Compression for an engine to run. Since this engine was just reassembled, there is a lot to question. Spark - rotor position - beware of caps where the points are not "straight through" plug wires in the correct position timing - may need play with it a bit coil - ensure it is firing spark plug firing - use a jumper to connect ...

The basic answer to your question is: Yes To be more specific, I cannot tell you if it will work or not. It appears you already have the specific dash version you want. What you can do is install it and see if it will work. What is the worst which can happen? If you are not modifying anything to fit the different gauge cluster, all you have to do is ...

Dodge installed VNT Turbochargers on cars in 89 and 90. The most well known of which is the 1989 Shelby CSX-VNT. The vanes were controlled by a dual port vacuum actuator. There was nothing electronic on the turbo itself, but there were vacuum solenoids (for boost control) on the lines going to the actuator. The VNT Turbo has movable vanes on the exhaust ...

Sounds like the temperature sensor is broken. A new one is $40-$55, and it's a 30 minute job to replace if you've never done it before (it lives behind the grill in front of the radiator). Not uncommon for these to fail on Subarus and give weird readings. Following Paulster2's comment, here's an image of what the sensor looks like; In this image (of a ...

The thermostat would have been my first guess too. It doesn't need a sealing ring, the housing will slightly clamp it when you put it back together. It is entirely possible that the temperature sensor has 'drifted' and is reading lower than the genuine temperature. I have experienced this more than once in my own cars. It's worth as try as they're usually ...

Yes, you can put them in the front bumper. You'll need to drill them in - just like the back bumper. I would recommend having a cut off switch for the front sensors somewhere in the cabin, otherwise the beeping would be very annoying. Rear sensors are (usually) powered by the reversing lamp's wiring, so in the front you won't have this... so a cut off ...

Disclaimer: I've never done this practically. This answer is based on my somewhat limited exposure to turbomachinery theory in automotive applications. It's all about the flow Unlike fixed-geometry turbos, in which the vanes provide optimal efficiency for a single flow, vane angles are adjusted in variable-geometry turbos to enhance efficiency across a ...

In a word? Nothing. I mean, a 4-wire O2 is going to be about the same no matter what it's made for. The connector may be different, but the guts are going to be pretty much the same. Unfortunately, you really need to know what works well with your vehicle. For instance, Bosch (from my understanding) originated the O2 sensor. Their product should be above ...

shows that a Citigo Elegance 75PS Greentech with 185/55 x 15" requires 26psi on its small/narrow tyres. You can go for the cheap option by searching for 26psi valve indicator caps which will allow you to visually inspect each tyre without having to get a pressure monitor to check them. Some aftermarket tyre pressure monitoring tools (such as this one) ...

The key to understanding this system is that the signal to the gauge unit comes from the PCM not the temp sensor. Testing is done at the connector at the PCM. Disconnect the “C” connector. Ground the C24 wire Y/G, turn the power on, Leave the ground connected for no more than 30 seconds. The gauge should move to Hot. If it does the gauge and wiring is OK....

It is more than likely not the sensor. The problem lies in the circuit which goes to the sensor. Replacing the sensor is probably the last thing I'd do in this case. In this case, I believe it is only a single wire you'd need to trace. It could also be the connector/connection at the sensor itself. In either case, it looks as though the intake manifold ...

The fact that the coolant temp is lower than the thermostat set point indicates that the thermostat isn't doing what it's supposed to do. Since you have verified that the thermostat fine by testing it in boiling water, the only logical explanation is that coolant flow is (at least partially) bypassing the thermostat. That thermostat gasket is essential in ...

I suspect that the sensors were detecting the loose paint as an object very close. You should be able to re-paint them, but I don't know if they would need a special sort of paint - it might be worth checking with Ford

This will not likely work. If the sensor is not the correct part number for the specific vehicle it is unlikely that it will match the exacting electrical specifications needed for the PCM to control and read the sensor. AFR sensors are matched to the PCM. Unlike so called "oxygen sensor" which can more often be interchanged across different engines and ...

A small portion of exhaust gas is sent back to the intake to improve emissions via the EGR hose. If your vehicle is running rich, some fuel will be left unburnt in the exhaust gases. This can explain the wet fuel that you are seeing on the MAP sensor. Unfortunately, this is an indication of bigger engine operability problems. It doesn't surprise me that ...

Engines need 4 things to run- spark (at the right time), air, fuel, and compression. A lot of things can conspire to deny some of those things. Don't just start shotgunning parts, that gets expensive real fast. Take a few moments to do diagnostics first. Once you find the category of problem, you've eliminated 3/4 of the possibilities, and tracking it down ...

The Vehicle Speed Sensor sends signal to the Instrument Cluster. You can check pin 2 (blue/white) on the B connector for signal from the VSS. If there is signal you need a new cluster. If not you have to check continuity between the cluster and VSS

Did you ever solve this problem? I have just had a customer buy some eBay Peugeot ABS sensors and they were completely faulty. Replaced with some OE quality (Pagid) sensors and the car was fine. I would suggest only using OE quality part or at least only buy parts from a decent motor factors.

It's certainly worth checking the ignition timing - one obvious possibility (though I'm sure you've checked this) is that the timing is 180 degrees out, so it's firing at the end of the exhaust stroke instead of the compression stroke. Otherwise, have you done a compression test since reassembling? I doubt there would be any problems there, but might be ...

The other answers have covered most things, but here are two points that haven't yet been mentioned. Warranty This is usually a function of the supplier rather than the manufacturer, but some places offer a lifetime guarantee. Others offer none. Physical fit How hard could it possibly be to make accurate threads? Apparently pretty hard for some ...

In general what do the more expensive sensors have that the cheaper ones don't? There is no functional difference; all 4-wire zirconia-based narrowbands should exhibit the following: useful voltage range 0.1 - 0.9 V stoichiometric AFR at 0.45 V low voltage = lean condition, high voltage = rich condition Certain brands may have a quicker warm-up time or ...

I had very similar symptoms on a BMW, the sensor itself was faulty and the problem was solved by replacing it. There are two ways of diagnosing this that I can think of: Look at the sensor readings in the live data section of a diagnostics tool If you don't have access to such a tool, buy one new sensor and fit it to each position one by one until the ...

If you are going back to the same source for the sensor, it could be there was a bad production run of the sensor: it could be a manufacturing defect. Try a different source for the sensor and see if it doesn't cure the problem. I agree this is a really strange issue. I have never seen where a single sensor would fail repeatedly. IMHO, it still boils down ...

A better way to handle this is to pull direct power from a fuse (or direct battery power with inline fuse or fusible link) and run it through a relay. Connect a power lead from the reverse lights to power the relay. When the lights come on, the reverse camera will be powered by battery power. The relay draws very little power and should not cause your ...

Rather than reprogram the ECU to ignore the sensor (which could then cause problems in the event there was a problem with your engine oil), why not simply replace the sensor. I'm sure it will be an inexpensive part when compared to the potential damage running with an unreported oil fault could cause. Also, as you say you've checked and replaced the sensor ...

I assume that by "air filter sensor" you're referring to the Mass Air Flow (MAF) sensor. If cleaning it helped temporarily, this is usually a sign that the sensor is on its way out and needs to be replaced. There is one test that you might be able to perform to corroborate that it is in need of replacement. Some vehicles are able to run in a fallback mode ...
