Just had the timing belt and crankshaft tensioner and starter replaced. Drove 150 miles with no problem. Now check engine light comes on again, engine smells like burning gas, and car cuts off while I am driving it and is rough driving off and on.

The reason I had all that replaced is because the check engine light was on and the car sometimes drove rough and the car sometimes didn't start.

Auto Zone codes came up as either an electrical problem or a crankshaft tensioner problem. My technician chose the latter and decided I needed a timing belt replacement since he was already in there.
Do you
have the same problem?

Hi kmgeiss,

What was the troubble code retrieved?

At 130k miles, the timing belt was overdue for replacement if it had not been done previously.

The problem was there before the replacement of the timing belt so it could be othere things.

Let me know the trouble code.

P1381. After replacing all that could my problem have been the distributor the whole time?

And how do I know if I just need to replace the cap or the whole distributor?

At this point I'm not trusting my mechanic. Could he have disrupted the distributor by replacing the timing belt, crankshaft positioner, and starter?

Or do you think it was the distributor the whole time?

The CYP is in the distributor and it is possibly a fault with it or its wiring circuit. A loose connection maybe.

Here are the diagnostic procedures.

DTC P1381 & P1382: CYP SENSOR
NOTE:
DTC P1381 indicates intermittent interruption in Cylinder Position (CYP) sensor circuit. DTC P1382 indicates no signal in CYP sensor circuit.

1. Perform PCM reset procedure. Start engine. If DTCs P1381 and/or P1382 are present, go to next step. If DTCs P1381 and/or P1382 are not present, problem is intermittent, system is okay at this time. Check for poor connections or loose wires at 14-pin connector (located at right shock tower), CYP
connector and PCM.

2. Turn ignition off. Disconnect distributor 4-pin (F22B2) or 5-pin (F22B1) connector. On F22B1, measure resistance between sensor terminal No. 4 (CYPP) and terminal No. 5 (CYPM). See Fig. 21
. On F22B2, measure resistance between sensor terminal No. 2 (CYPP) and terminal No. 4 (CYPM). See Fig. 22. If resistance is 800-1500 ohms, go to
next step. If resistance is not as specified, replace distributor ignition housing.

3. Check for continuity between ground and CYP sensor terminal No. 2 and terminal No. 4 (F22B1) or terminal No. 4 and terminal No. 5 (F22B2), individually. See Fig. 21 or Fig. 22. If continuity does not exist, go to next step. If continuity exists, replace distributor ignition housing.

4. Reconnect distributor 4-pin or 5-pin connector. Disconnect PCM 31-pin connector "C". See Fig. 3. Measure resistance between PCM connector terminal C4 and terminal C14. If resistance is 800-1500 ohms, go to next step. If resistance is not as specified, repair open in suspect wire(s) between distributor and PCM.

5. Check for continuity between ground and PCM 31-pin connector "C" terminal C4. If continuity exists, repair short in wire between distributor and PCM. If continuity does not exist, substitute a known-good PCM and recheck. If symptom or problem goes away, replace original PCM.

It seems that sometimes (25%) the code is P1381 and the red light is on and 75% of the time it just reads a question mark on the code reader with a yellow light.

What does that mean?

Sorry I am not familiar with the scanner that you are using so I am not able to tell you what it is.

The % of the fault is what the indication means, intermittent failing and it could be any loose or contaminated wire connections.

Perform the diagnostics outlined above to see if you can come up with anything.

Does this always mean the cars computer needs replacing?

That's the only code I get now. Then I get a notice that says 'read' which the manual says it means it can't connect to the computer.

The car won't start now. It just tick, tick, tick, ticks like the starter needs replacing. Just replaced that though.

Looks like you have a weak battery. Did you try jump starting?

The PCM seldom malfunctions so we should leave that out for the time being.

Inability to communicate such as data link error could be due to imcompatible scanner, loss of power supply to the Diagnostic Link Connector or a bad PCM.

Try manually retrieving the trouble codes to see if it works. Use a jumper wire to jump Terminal #4 and #9 of the DLC and turn ignition switch ON to see if the CEL ( MIL) blinks any code.
