Question about 2004 Jeep Grand Cherokee

2 Answers

Engine light comes on for the throttle (TSP) has low voltage. Changed the TSP and the car continues to say the same error. When the jeep starts to accelerate, it starts to skip.

    did you change it or did a mechanic change it. questions is if you changed it did you disconnect the negative battery terminal? usually when u disconnect it, it will reset itself and recognize the new tps, i just changed mine yesterday, had the same problem.

You may have another sensor dragging the voltage down to all the sensors.Hook a voltmeter to the TPS reference wire and a good ground and with the switch on engine off you can unhook a sensor one at a time to see if your voltage comes up.

The engine coil needed to be replaced. Unfortunately, this is an expensive fit, but there was no power getting to the engine.

TSP.. tail spin propeller?

tps is throttle position sensor, or tire pressure sensor of the TPMS system.

why not say , where you say or head this word.
so we can stop guessing.
or point to it.
or photo it.

Just scanned my 1999 300m. It went into safe mode while me wife was driving it home- 2nd gear only. It had a code P1714 and P0700 come up on the scanner. I can't find anything about the P1714.

Check engine light comes on after approx. one minute. My code reader gives me a 214 in continuous memory ( cylinder ID circuit failure). I clear the code and it comes back. What is giving me this code?...


look 214 is not a valid code for a 1995 escort, this is an OBD1 system. here is a list of trouble codes for this year of ford no matter the model.

You should find the diagnostic connector under your hood normally by the fender on the battery side. By just using your test light and a jumper wire, it will tell you what kind of problem you got.

KEY ON ENGINE OFF (KOEO) TEST
Model years 1984-1995 all models of Ford
1. Make sure engine is fully warmed. If in doubt, run engine at 2000 rpm for 2 minutes.
2. Turn ignition off and wait 10 seconds for system to shut off. Make sure A/C is off and transmission is in Park (automatic) or Neutral (manual).
3. Hook up light and jumper (or a tester if you have one). Turn key to ON (do not start engine). Read the codes.

How to do it?

Example code 23: your test light should flash 2 long consecutive flashes followed by 3 short pulses.

Describe your 1997 Jeep Wrangler 1997 jeep wrangler 4 cyl idle fluctuates 900 rpm to 400 rpm after warmup no service engine light but check guages light comes on momentarily when rpm gets low and oil press...


The check gauges light is normal because at 400 rpm it isn't running fast enough to build sufficient oil pressure. I am guessing maybe a vaccum leak???

2004 Honda Civic -Code P0122 Throttle Position Sensor Voltage Low


yes, this is the case of a failed throttle body, in which case it needs replaced, the car is getting too much fuel causing the high idle. this needs replaced asap. you could proably find a small independant honda shop that could do the work for less.

2000 jeep grand V8 low idle then dies


A faulty gas cap can cause the sensor to come on.
Clean out the throttle body with a cleaner and see if the idle improves.

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.
