95 4cyl camry intermittant spark loss thus engine dies and fails to crank for short period, sometimes can be coaxed to crank again after removing negative battery terminal for several minutes and replacing it, although this does not always work and frequently, the car will again die within minutes and sometimes will not crank again for half an hour or so. This time, the problem occurred after the weather became damp..... Suggestions?

Test the crankshatt position sensor. If it tests good, please get back to us.

OPERATION The Crankshaft Position (CKP) sensor provides a signal through the ignition module which the ECM uses as a reference to calculate rpm and crankshaft position.

TESTING The crankshaft sensor should be tested either cold 14-122°F (-10-50°C) or hot at 122-212°F (50-100°C).

  1. Using an ohmmeter, measure the resistance between terminals. Resistance cold should read 1630-2740 ohms and hot; 2060-3225 ohms.
  2. If resistance is not within specification, the sensor may be faulty.
REMOVAL & INSTALLATION See Figure 1

Fig. Fig. 1: The crankshaft position sensor is located to the right of the water pump-1MZ-FE engine
  1. Disconnect the negative battery cable.
  2. Remove the right hand engine under cover.
  3. Remove the right side fender apron seal.
  4. Remove the sensor wiring retaining nuts.
  5. Remove the bolt and disconnect the crankshaft position sensor wiring, then withdraw the sensor.
To install:
  1. Install the sensor and secure with the bolt to 69 inch lbs. (8 Nm).
  2. Attach the engine wiring.
  3. Install the right hand fender apron seal.
  4. Install the right hand engine under cover.
  5. Connect the negative battery cable.
  6. Reset any electrical components such as the radio or clock.

SOURCE: How do I change the starter in a 2000 Toyota Camry LE

i'm sure it's not the starter itself that is the problem, have the stater's solenoid checked...it might be stucked. It's quite a lot of work removing the starter but you can do it if you are willing enough to learn. You just need the right idea and tools to do it. Hope this will help save you bucks!

CAR DIED WHILE DRIVING,will not restart ,crank shaft very hard to turn by hand with all belts off timing belt and timing marks are perfect.3.0l camry


Oooh, your timing belt is OK? and the engine is hard to turn? You may have suffered an engine seizure due to oil starvation. Some Toyota Camry engines around this year suffered bad sludging, leading to this. If you take the spark plugs out, place the trans in neutral, and the engine is still hard to turn at the crank pulley, oooh, I think it is partly seized, sorry.

If not, I think the timing belt jumped a tooth or 2 (if old), or the fuel supply dropped pressure, or the spark failed at the igniter.

I agree it sounds like the magnet for the cam sensor, or a problem in the wiring harness.
I don't think the engine will run with the cam sensor disconnected since it needs that signal to set base timing. It can run without the crank sensor once the engine starts.
There is a slight chance the timing chain is getting loose and affecting cam timing too. You may be loosing plastic teeth on the cam gear.

1993 Toyota camry will not start


Check to see how much spark you have. Spark should jump at least a 3/4" inch gap. If it only jumps an eighth to a quarter inch or less than you have weak spark. If the coil is external replace it if the coil is inside the distributor replace the distributor. I almost guarantee this is a week spark issue.

Engine cranks. sparks but does not start. fuel pressure ok


Have you replaced the crank sensor? The crank sensor on top of the trans. bell housing does control the injector pulse through the ECM.
The sensor is a common problem with the Jeeps. Sometimes the sensor stops working when the engine is hot and will start again when it cools off and sometimes it dies from oil leaking on top of it or it just dies.

Trouble codes


Trouble Code: P0139
O2 (B1 S2) Slow Response
Trouble Code Conditions:Engine started; vehicle driven at 20-55 mph with the throttle open for 2 minutes; ECT at more than 158ºF (70C); catalytic converter temperature is more than 1112F (600C); and EVAP purge is active. O2 Sensor signal voltage switches less than 16 times from lean to rich within 20 seconds during monitoring, or will compare the state of change between the front and rear O2 Sensors and if the differences are greater than a calibrated amount, the DTC will set. 3 good trips are required to turn off the MIL.
Possible Causes:
  • Exhaust leak
  • O2 element is contaminated, deteriorated or it has failed
  • O2 signal circuit or return circuit has failed

Trouble Code: P0344
Camshaft Position Sensor Circuit Intermittent
Trouble Code Conditions:Engine cranking or running; system voltage over 10.5v. The PCM detected an intermittent loss of the CMP Sensor signal during the period of 2.5 complete engine revolutions. The failure counter must reach 20 before this code matures and a code is set.
Possible Causes:
  • Wiring harness fault
  • 5v supply circuit open or shorted to ground
  • Tone wheel/pulse ring is damaged or corroded
  • CMP Sensor has failed
  • CMP Sensor signal circuit is open, shorted to ground or battery voltage or 5v supply
  • CMP Sensor ground circuit is open
  • PCM has failed
  • Trouble Code: P0340
    No Camshaft Position Sensor Circuit Failure
    Trouble Code Conditions:Engine cranking or running, system voltage over 10v. The PCM detected CKP pulses without detecting any CMP Sensor pulses for 5 seconds or 2.5 engine revolutions.
    Possible Causes:
  • CMP Sensor connector is damaged, open or it is shorted
  • CMP Sensor signal circuit is open or shorted to ground or to battery voltage or 5v supply circuit
  • CMP Sensor 5v supply circuit is open or shorted to ground or to battery voltage
  • CMP Sensor ground circuit is open
  • CMP Sensor is damaged or has failed
  • CKP Sensor is damaged or has failed
  • PCM has failed
Good luck....
